ABSTRACT:
A process is provided for preparing monohydrocarbyltin trihalides, RSnX.sub.3, wherein R is an alkyl, cycloalkyl, alkaryl, aryl or aralkyl group of 1-24 carbon atoms, and X is a halogen atom by the redistribution reaction between a tetrahydrocarbyltin, R.sub.4 Sn, a trihydrocarbyltin halide, R.sub.3 SnX, or a dihydrocarbyltin dihalide, R.sub.2 SnX.sub.2, and a tin tetrahalide, SnX.sub.4, in the presence of sulfonium or isothiuronium salts as catalysts.
