ABSTRACT:
Organotin derivatives of mercaptoalcohol esters that correspond to the general formula ##STR1## wherein R and R' are hydrocarbon and m is 2 or 3, are prepared by sequentially reacting a monoorganotin trihalide with stoichiometric amounts of a base, a mercaptoalcohol, an alkali metal sulfide or disulfide and a carboxylic acid or an ester thereof. The present method offers advantages over the prior art, which teaches reacting an esterified mercaptoalcohol with an organotin halide, oxide or organostannoic acid. Compounds wherein R' is n-heptyl are unique in that they do not exhibit the disagreeable odor that characterizes this class of compounds.
