A novel synthetic method of 2,4-disubstituted oxazoles using carboxylic acid-derived Bu2Sn[OC(O)R]2
A novel synthetic method for the preparation of 2,4-disubstituted oxazoles was developed, entailing the reaction of dibutyltin diacylates Bu2Sn[OC(O)R]2 with 1-substituted acetylenes and TMSN3 to afford a range of 2,4-disu
New latent organotin catalysts: Preparation and mechanism of the thermal decomposition of bis(2-(acyloxy)alkyl)diorganotins
New organotin compounds, bis(2-(acyloxy)alkyl)diorganotins, can be thermally decomposed into diorganotin dicarboxylates. The substituent effects on the reaction parameters are studied, and a possible mechanism for the decomposition is proposed. These tetr
