Process for preparing organotin esters

摘要

Organotin esters from acid esters of di or poly carboxylic acids are made by adding a base to a mixture of an organotin halide and the acid ester in the presence of water, and reacting to form the organotin ester, the amount of base and acid ester being to provide 0.9-1.3 equivalents and at least 0.9 equivalents respectively per g. atom of halogen in the organotin halide, and the conditions being such as not to cause substantial hydrolysis.
