ABSTRACT:
Organotin derivatives of mercaptoalcohol esters corresponding to the general formula ##STR1## WHEREIN R and R' are hydrocarbon, m is 2 or 3 and q is 1 or 2 are prepared by reacting a mercaptoalcohol of the formula HS(CH.sub.2).sub.m OH with a diorganotin oxide, organostannoic acid or an anhydride of said acid in an aqueous medium and subsequently esterifying the reaction product with the desired carboxylic acid, R'COOH, or an ester thereof. The present method offers advantages over the prior art, which teaches reacting an esterified mercaptoalcohol with an organotin compound. Compounds wherein R' is n-heptyl are unique in that they do not exhibit the disagreeable odors that characterize this class of compounds.
