The C-Sbondformation reaction has been described by the reaction of Bromo-barbituric acid with ammonium aryl dithiocarbamates in the presence of Amberlyst-15 as a reusable catalyst in aqueous medium. The mild reaction conditions, easy product isolation and good to high yields, are the major advantages of present protocol.

We have investigated the pairs of rotational isomers for six 3-(o-aryl)-5-methyl-rhodanines (Z = H, F, Cl, Br, OH, and CH3) using NMR spectroscopy and density functional theory (DFT) calculations. Electron density topological and NBO analysis has demonstrated the importance of non-covalent interactions, characterised by (3, -1) bond critical points (BCPs), between the oxygen and sulfur atoms on the

Abstract Tris[N(o-, m-, p-chlorophenyl)dithiocarbamato] complexes of Au (III) and As(III) have been synthesized and characterized. Thermal behaviour of these complexes have been investigated by TG and DTA techniques in static air atmosphere.
