O consumo colaborativo como alternativa ao consumo de massa: a percepção do consumidor em bairros de Florianópolis e a relação do consumo colaborativo com valores pessoais.

TCC (graduação) - Universidade Federal de Santa Catarina. Centro Sócio-Econômico. Economia.O tipo de consumo que a sociedade habituou-se ao longo das últimas décadas tem ocasionado problemas que impactam diretamente o cotidiano das pessoas. Alavancado por motivações individuais e questões ambientais, sociais e econômicas, o consumo colaborativo é um fenômeno recente que vem alterando o funcionamento da economia global ao proporcionar aos consumidores uma nova forma de acomodar seus desejos e necessidades de maneira conveniente e sustentável. Associado a isso, as redes de informação energizadas pela Internet têm modificado significativamente o modo e a velocidade com que os agentes econômicos se relacionam. Nesse sentido, o objetivo maior deste trabalho de conclusão do Curso de Ciências Econômicas é identificar a percepção dos consumidores da Grande Florianópolis acerca do consumo colaborativo como alternativa ao modelo de consumo tradicional. O estudo é dividido em três partes principais. Inicialmente recorre-se a pesquisa bibliográfica para contextualizar e conceituar os termos economia compartilhada e consumo colaborativo, suas formas e princípios. Visando conhecer os efeitos desse movimento no Brasil e especificamente em Florianópolis, na sequencia realiza-se pesquisa através de questionários para identificar a propensão do consumidor a participar de práticas de consumo colaborativo em quatro regiões: Lagoa da Conceição, Centro, Trindade e Continente. Considerando que os valores pessoais interferem no comportamento do consumidor, busca-se avaliar qualitativamente de que forma tais valores se relacionam com a disposição dos mesmos a participar do consumo colaborativo. Através do questionário aplicado, ainda que com amostra limitada, observa-se que os consumidores apresentam de modo geral nível satisfatório de propensão a participar do consumo colaborativo, sendo a Lagoa da Conceição a localidade com maior adesão, seguida por Continente, Trindade e Centro. Além disso, a mensuração dos valores pessoais permite observar que os consumidores mais abertos a mudança, menos conservadores e menos apegados materialmente apresentam maior propensão a participar do consumo colaborativo, como é o caso da Lagoa da Conceição. As considerações finais discutem os principais achados e limitações do estudo

Collective Approach to Advancing C–H Functionalization

C–H functionalization is a very active research field that has attracted the interest of scientists from many disciplines. This Outlook describes the collaborative efforts within the NSF CCI Center for Selective C–H Functionalization (CCHF) to develop catalyst-controlled selective methods to enhance the synthetic potential of C–H functionalization

Enantioselective Synthesis of 2‑Arylbicyclo[1.1.0]butane Carboxylates

The rhodium-catalyzed reaction of 2-diazo-5-arylpent-4-enoates can be controlled by the appropriate choice of catalyst and catalyst loading to form either 2-arylbicyclo[1.1.0]butane carboxylates or cyclohexene derivatives. Both products are produced in a highly diastereoselective manner, with 2-arylbicyclo[1.1.0]butane carboxylates preferentially formed under low catalyst loadings. When the reaction is catalyzed by Rh₂(<i>R</i>-BTPCP)₄, the 2-arylbicyclo[1.1.0]butane carboxylates are generated with high levels of asymmetric induction (70–94% ee)

Rh₂(<i>R</i>‑TPCP)₄‑Catalyzed Enantioselective [3+2]-Cycloaddition between Nitrones and Vinyldiazoacetates

Rhodium-catalyzed reaction of vinyldiazoacetates with nitrones results in a formal [3+2]-cycloaddition to generate 2,5-dihydroisoxazoles with high levels of asymmetric induction. The cascade reaction begins with a vinylogous addition event, followed by an iminium addition ring-closure/hydride migration/alkene isomerization cascade. Dirhodium tetrakis­(triarylcyclo­propanecarboxylates) are the optimum catalysts for this process

Silver-Catalyzed Vinylogous Fluorination of Vinyl Diazoacetates

A silver-catalyzed vinylogous fluorination of vinyl diazoacetates to generate γ-fluoro-α,β-unsaturated carbonyls is presented. Application of this method to the fluorination of farnesol and steroid derivatives was achieved

Role of Sterically Demanding Chiral Dirhodium Catalysts in Site-Selective C–H Functionalization of Activated Primary C–H Bonds

The influence of sterically demanding dirhodium tetracarboxylate catalysts on the site selectivity of C–H functionalization by means of rhodium carbene-induced C–H insertion is described. The established dirhodium tetraprolinate-catalyzed reactions of aryldiazoacetates cause preferential C–H functionalization of secondary C–H bonds as a result of competing steric and electronic effects. The sterically more demanding dirhodium tetrakis­(triarylcyclopropanecarboxylate) catalysts, exemplified by dirhodium tetrakis­[(<i>R</i>)-(1-(biphenyl)-2,2-diphenylcyclopropanecarboxylate)] [Rh₂(<i>R</i>-BPCP)₄], favor C–H functionalization of activated primary C–H bonds. Highly site-selective and enantioselective C–H functionalization of a variety of simple substrates containing primary benzylic, allylic, and methoxy C–H bonds was achieved with this catalyst. The utility of this approach has been demonstrated by the late-stage primary C–H functionalization of (−)-α-cedrene and a steroid

2,2,2-Trichloroethyl Aryldiazoacetates as Robust Reagents for the Enantioselective C–H Functionalization of Methyl Ethers

A new class of reagents is described for C–H functionalization by means of C–H insertion using donor/acceptor-substituted rhodium­(II) carbene intermediates. The 2,2,2-trichloro­ethyl aryl and heteroaryl diazoacetates, together with the dirhodium triaryl­cyclo­propane carboxylate catalyst Rh₂(<i>R</i>-BPCP)₄, enabled the enantioselective intermolecular C–H functionalization of a range of methyl ethers with high levels of site selectivity and enantioselectivity
