Suzuki-Miyaura and Heck-Mizoroki C-C cross-coupling reactions of 4-(halophenyl)-1,3-thiazoles with aryl(hetaryl)boronic acids or olefins, respectively, were investigated by using a catalytically active benzimidazole-based palladium(II) complex under both thermal and microwave heating conditions in water. The factors affecting the optimization of such reactions were evaluated. palladium - homogeneous

A simple and efficient one-pot protocol has been developed for the conversion of styrenes into 4-aryl-2-aminothiazoles using readily available starting materials. Tribromoisocyanuric acid was successfully used for the co-bromination and oxidation of styrenes to give phenacyl bromides, which in the presence of thioureas produced the corresponding 4-aryl-2-aminothiazoles in 48–70% yield. The protocol

desulfurizing agent in the preparation of organic cyanamides and substituted thiazoles starting from dithiocarbamicacidsalts. In this approach, alkyl/aryl isothiocyantes were first obtained by the desulfurization of dithiocarbamicacidsalts with EDPBT. The in situ–generated isothiocyanates reacts with an aqueous ammonia, forming alkyl or aryl thioureas, which on subsequent oxidative desulfurization
copper-catalyzed coupling of oximeacetates with isothiocyanates. Various 4-substituted and 4,5-disubstituted 2-aminothiazoles were formed smoothly under mild reaction conditions. This process involved copper-catalyzed N–O bond cleavage, activation of vinyl sp2 C–H bonds, and C–S/C–N bond formations. It is noteworthy that the oximeacetates were used not only as a substrate but also as a single oxidant
