Evaluation of Antibacterial Properties of Triorganotin Carboxylates Containing Functionalised Ester Groups in Tests Against Some Pathogenic Bacteria
Autor: Joyce Koshy, A. Ansary, Kong Mun Lo, V. G. Kumar Das
Publikováno v: Metal-Based Drugs
Bacterial screening employing the agar diffusion test on triphenyltin carboxylates containing various functional residues in the ester moiety revealed appreciable differences in their activities relative to triphenyltin acetate. Among these, [3-(Diet

Studies on the transesterification of glycerides: I. The methanolysis of tripalmitin catalysed by diorganotin(IV) compounds
Autor: V. G. Kumar Das, Chai Hon Yean
Publikováno v: Applied Organometallic Chemistry. 14:304-315
The potential of diorganotin compounds, in particular alkoxides and phenoxides, to function as neutral and non-corrosive catalysts in the methanolysis of tripalmitin (the main triglyceride in palm oil) to methyl palmitate has been investigated. The c
