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.
