Abstract of the Disclosure It is known to prepare triorgans tin halides wherein the hydrocarbon group bonded to the tin is (1) cycloalkyl, (2) cycloalkyl, alkyl or a mixture thereof, or (3) a combination of groups differing in molecular weight by at least 42. The present invention provides a process for preparing tri(B- substituted phenethyl)tin halides such as trineophyltin chloride by reacting three moles of the corresponding organomagnesium halide for every mole of an organotin trihalide containing an alkyl or a phenyl group bonded to the tin atom. The resultant tetraorganotin compound is reacted with an anhydrous stannic halide in a hydrocarbon diluent and the desired triorganotin halide is isolated following hydrolysis of the reaction mixture.
