Synthesis, Characterization And Computational Studies Of Novel (E)-N-(3,4-Dimethoxybenzylidene)naphthalen-1-amine

Novel (E)-N-(3,4-dimethoxybenzylidene)naphthalen-1-amine (DBNA) ligand has been synthesized by refluxing 1-naphthylamine and 3,4-dimethoxybenzaldehyde in methanolic solution for 5-6 hours. The obtained compound was characterized by UV-Vis, FT-IR and 1H-NMR. All the spectral data confirmed the structure of the ligand

Novel Unsymmetrical Ru(III) and Mixed-valence Ru(III)/Ru(II) Dinuclear Compounds Related to the Antimetastatic Ru(III) Drug NAMI-A

In this paper we report the stepwise preparation and the characterization of new unsymmetrical monoanionic Ru(III) dinuclear compounds, [NH4][{trans-RuCl4(Me2SO-S)}(μ-L){mer-RuCl3(Me2SO-S)(Me2SO-O)}] (L = pyz (1), pym (2)). By a similar synthetic approach we also prepared new mixed-valence Ru(III)/Ru(II) dinuclear compounds of formula [NH4][{trans-RuCl4(Me2SO-S)}(μ-pyz){cis,cis,cis-RuCl2(Me2SO-S)2(CO)}] (L = pyrazine (pyz, 3), pyrimidine (pym, 4)). Moreover, we describe the chemical behavior of compounds 1-4 in physiological solution, also after complete reduction (with ascorbic acid) to the corresponding Ru(II)/Ru(II) species. Overall, the chemical behavior of 1 and 2 after reduction resembles that of the corresponding dianionic and neutral dinuclear species, [{trans-RuCl3(Me2SO-S)}2(μ-L)]2−and [{mer-RuCl3(Me2SO-S)(Me2SO-O)}2 (μ-L)]. On the other hand, the mixed-valence dinuclear compounds 3 and 4, owing to the great inertness of the cis,cis,cis-RuCl2(Me2SO-S)2(CO)(1/2μ-L) fragment, behave substantially like the mononuclear species [trans-RuCl4(Me2SO-S)(L)]− in which the terminally bonded L ligand can be considered as bearing a bulky substituent on the other N atom

Destination encounters with local food: the experience of international visitors in Indonesia

Increasing numbers of visitors are seeking out culinary experiences when travelling overseas. Food can enhance the destination experience, giving physiological sustenance and providing opportunities to learn about destination cultures through direct encounters with local cuisines. However, engaging with novel local food might arouse certain visitor expectations, particularly among those who have not visited previously. This study aimed to identify international visitor preconceptions of local Indonesian food and the underlying factors influencing expectations prior to their in-country experience of dining on local food. A questionnaire-based survey that was administered to 349 international visitors identified seven factors underlying their expectations: staff quality, sensory attributes, food uniqueness, local servicescapes, food authenticity, food familiarity, and food variety. A number of significantly different dining expectations were also highlighted between first-time and repeat visitors.</jats:p

Pyridylporphyrins peripherally coordinated to ruthenium-nitrosyls, including the water-soluble Na4[Zn\ub74'TPyP{RuCl4(NO)}4]: synthesis and structural characterization.

Several new ruthenium-nitrosyl conjugates with meso-4'pyridylporphyrins, namely the two anionic isomers [nBu4N][trans-RuCl4(4'MPyP)(NO)] and [nBu4N][cis-RuCl4(4'MPyP)(NO)] , the two neutral isomers [mer,trans-RuCl3(4'MPyP)2(NO)] and [mer,cis-RuCl3(4'MPyP)2(NO)], and the tetraruthenated adduct [nBu4N]4[4'TPyP{RuCl4(NO)}4] were obtained by reaction of [nBu4N][trans-RuCl4(dmso)(NO)] with 4'MPyP and 4'TPyP (meso-4'monopyridylporphyrin and meso-4'tetrapyridylporphyrin, respectively). Exchange of nBu4N+ for Na+ eventually led to the water soluble tetraruthenated porphyrin Na4[Zn 4'TPyP{RuCl4(NO)}4]
