Tin—sulfur bonds

Organotin compounds with tin-sulfur bonds are useful for the transformations of alkyl halides to sulfides (eq (119)) [114], esters to thiolesters (eq (120)) [115], and acetals to monothioacetals (eq (121)) [116]. 

Organotin compounds that are salts of alkyltin oxides with carboxylic acids (e.g., dioctyltin dilaurate) are usually called organotin carboxylates. Organotin compounds with at least one tin-sulfur bond (e.g., dioctyltin octylthioglycolates) are generally called organotin mercaptides. The latter are considered to be the most efficient and most universal heat stabilizers. The important products which are on the market have the following structures ...
