Abstract

The transesterification of carboxylic esters and the esterification of carboxylic acids are effected under mild conditions under catalysis by l, &disubstituted tetraalkyldistannoxanes 1. Various functional groups remain unaffected and otherwise difficult to obtain esters are accessible. An ester bearing a tertiary butyl group in the carboxylic acid moiety remained unchanged in competition experiments with a less bulky ester, which undergoea ...
