Copper-iron mixed oxide supported onto cordierite honeycomb as a heterogeneous catalyst in the Kharasch-Sosnovsky oxidation of cyclohexene

A copper-iron mixed oxide was deposited by the washcoating procedure over cordierite honeycomb monoliths for its use as a heterogeneous catalyst in organic synthesis processes. In particular, the prepared catalyst, characterized by techniques such as X-ray fluorescence, X-ray diffraction, SEM-EDS, laser granulometry, adherence tests, Temperature-Programmed Oxidation and Temperature-Programmed Reduction, showed an excellent yield and stability in the selective production of the allylic ester derived from the Kharasch-Sosnovsky oxidation of cyclohexene with benzoic acid. The use of a structured catalyst here proposed opens up an interesting alternative to homogeneous catalysis in the field of synthetic chemistry. © 2021 The AuthorsThe authors thank the Ministry of Economy and Competitiveness of Spain (Projects MAT2017-85-719-R , and AGL2017-88083-R ), the Junta de Andalucía ( FQM-110 and FQM-169 groups), and the Institute of Electron Microscopy and Materials (IMEYMAT) of Cadiz University (UCA) (Projects HOMOGREEN and NUPRECAT) for their financial support.

Acyloxylation of 1,4-Dioxanes and 1,4-Dithianes Catalyzed by a Copper−Iron Mixed Oxide

The use of a copper−iron mixed oxide as a heterogeneous catalyst for the efficient synthesis of α-acyloxy-1,4-dioxanes and 1,4-dithianes employing t-butyl peroxyesters is reported. The preparation and characterization of the catalyst are described. The effect of the heteroatoms and a plausible mechanism are discussed. The method is operationally simple and involves low-cost starting materials affording products in good to excellent yields

DoE (Design of Experiments) Assisted Allylic Hydroxylation of Enones Catalysed by a Copper–Aluminium Mixed Oxide

The allylic hydroxylation of enones using dioxygen as the oxidant has been studied. The reaction was first examined in the absence of any catalyst, using β-ionone as a model substrate. Then a new copper–aluminium mixed oxide, Cu–Al Ox, was prepared and characterized in order to be used as a catalyst. This oxide showed good activity, and provided the corresponding γ- or ε-hydroxylated enones, starting from different α,β- or α,β,γ,δ-unsaturated ketones. In all cases, the yields were significantly improved compared to experiments run in the absence of the catalyst. The reaction was selective, and the formation of epoxides or other overoxidation products was detected only to a minor extent. The described procedure is a technically straightforward synthetic alternative to those methods described to date involving many reaction steps or toxic reagents. The reactions were optimized using design of experiments techniques (DoE)

Prevalência dos tipos sangüíneos A, B e AB em gatos domésticos mestiços da cidade de Porto Alegre, Rio Grande do Sul, Brasil

O presente estudo teve como objetivo determinar a prevalência dos tipos sangüíneos em felinos domésticos, mestiços, da cidade de Porto Alegre, Rio Grande do Sul, Brasil. Foram selecionados aleatoriamente 100 gatos, clinicamente saudáveis, mestiços e sem parentesco entre si. Amostras de sangue foram coletadas da veia jugular e a tipagem sangüínea foi realizada através do teste RapidVet H Feline (DMS Laboratories, Flemington, USA) e do teste hemaglutinação em tubo de ensaio. A tipagem reversa foi realizada para confirmar o tipo e a presença de aloanticorpos naturais. No presente estudo encontrou-se prevalência de 97% e 3% de gatos do tipo A e B, respectivamente. Não foram encontrados gatos do tipo AB. Os resultados indicam que no sul do Brasil há uma alta prevalência de gatos domésticos mestiços do tipo A, entretanto a prevalência de gatos do tipo B encontrada no trabalho é mais alta do que aquelas relatadas em alguns países. O conhecimento da prevalência dos tipos sangüíneos da população de gatos de uma região pode auxiliar na determinação dos riscos de reações transfusionais e de ocorrência de isoeritrólise neonatal, e estes podem ser prevenidos através de tipagem sangüínea e teste de compatibilidade sangüínea.The present study was carried out to determine the prevalence of the blood types in mixed breed domestic cats of Porto Alegre, Rio Grande do Sul, Brasil. A hundred of clinically healthy mixed breed and non-related cats were selected. Blood samples were collected from the jugular vein and the blood typing was performed by RapidVet H Feline test (DMS Laboratories, Flemington, USA) and by hemagglutination tube test. Reverse blood typing was done to confirm the blood types and the presence of alloantibodies. In the present study the prevalence of blood type A and B in cats were 97% and 3%, respectively. No AB blood type cats were found. These results indicate that there is a high prevalence of blood type A mixed breed domestic cats in the south of Brazil, although the prevalence o B cats found is higher than reported in some countries. The knowledge of feline blood types prevalence in cat population can help to determine the risks of transfusion reactions and neonatal isoerythrolysis, and these can be avoid by blood typing and cross-matching test

Carbon integral honeycomb monoliths as support of copper catalysts in the Kharasch–Sosnovsky oxidation of cyclohexene

Carbon integral honeycomb monoliths prepared from a natural coal were employed as support of copper catalysts for organic synthetic purposes. In particular good to excellent yields (60–100% as function of the carboxylic acid employed) were obtained in the preparation of allylic esters by the Kharasch–Sosnovsky oxidation of cyclohexene. Different characterization techniques such as chemical analysis by Inductively Coupled Plasma Spectroscopy, nitrogen physisorption, X-ray Diffraction with Rietveld analysis, X-ray Photoelectron and Raman Spectroscopies, Temperature-Programmed Reduction and Scanning Electron Microscopy allowed finding that key parameters such as textural properties, degree of copper precursor decomposition and active phase homogeneity and dispersion can be modulated as function of a simple synthetic variable: the method used to dry the monoliths after impregnation with the metal precursor, either conventional or using microwaves. The results obtained allow understanding the key role of the nature and chemical surrounding (O2 anions or OH groups) of Cu2+ ions in the catalytic activity in the reaction investigated as well as the operating deactivation mechanisms. The use of the structured catalysts here proposed also opens up an interesting alternative to homogeneous catalysis in the field of organic synthesis

Estudo comparativo entre sutura manual e mecânica de coto brônquico em cães submetidos à pneumonectomia esquerda: avaliação histopatológica do pulmão direito e avaliação eletrocardiográfica

The study had purpose to evaluate the possible electrocardiographical alterations and the histopathological alterations in the lung of dogs submited by left pneumonectomy with comparative approach between two types of suture of bronchial stamp (manual and mechanical). We used twelve dogs, males and females, adults, mongrel dogs, weighting between 15 and 20 kilograms and evaluated the macroscopic alterations of right lung and the alterations of electrocardiogram. All animals showed clinical condition satisfactory in the post operated time. The electrocardiographical alterations were deviation of cardiac axis, sinoatrial block and miocardial isquemia. The histopathological alterations were pulmonary atelectasis, proliferations of bronchiole epithelium tended to obliterations and pulmonary emphysema. The study suggested that right lung was submited to pulmonary hipertension.O presente estudo teve como objetivo avaliar as possíveis alterações eletrocardiográficas e as alterações histopatológicas no pulmão de cães submetidos à pneumonectomia esquerda em abordagem comparativa entre dois tipos de sutura de coto brônquico (manual e mecânica). Foram utilizados doze cães, machos e fêmeas, adultos, sem raça definida, pesando entre quinze e vinte quilos sendo avaliados as alterações microscópicas apresentadas pelo pulmão direito e as alterações do eletrocardiograma. Todos os animais apresentaram-se em condições clínicas satisfatórias no período pós-operatório. As principais alterações eletrocardiográficas observadas no período pós-operatório foram desvio de eixo cardíaco, bloqueio sinoatrial e isquemia de miocárdio. No exame histopatológico, constatou-se atelectasia pulmonar, proliferação de epitélio de bronquíolo tendendo à obliteração, bronquiolite obliterante e enfisema pulmonar. O estudo sugere ainda que o pulmão direito foi submetido à hipertensão pulmonar
