Thallium compounds as catalysts for transesterifications and ester exchange reactions The transesterification of di-, tri- and tetracarboxylic alkyl esters with 2,3-epoxy-propanol was investigated in the presence of various metal compounds as catalysts. It was found that only thallium compounds catalyse the reactions under mild conditions without decomposition of 2,3-epoxypropanol. Many thallium compounds also proved to be very good catalysts for the reactions of 2,3-epoxypropanol with alkoxysilanes and the ester exchange reactions of di-, tri- and tetracarboxylic alkyl esters with 2,3-epoxypropyl-acetate. 相似文献

Reactions of CF3IOF2 with Fluoride Ion Acceptors: A New Method for the Preparation of Iodosyl Compounds CF3IOF2 reacts with the Lewis acids BF3, AsF5 and SbF5 to form the iodosyl compounds IO[BF4], IO[AsF6], IO[SbF6], and IO[Sb2F11]. The conditions of the preparation, the 19F-n.m.r. spectra, the Raman spectra and the thermal decomposition of the new compounds are described. 相似文献
