Abstract
Tri(.beta.-substituted phenethyl)tin halides such as trineophyltin chloride are prepared 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.
Claims5
A method for preparing a triorganotin halide of the general formula ##STR6## wherein R.sup.1 represents hydrogen or methyl, R.sup.2 is selected from the group consisting of hydrogen, alkyl contaning from 1 to 6 carbon atoms and X is chlorine or bromine, said method consisting essentially of the following steps:
- 1. Reacting at least three moles of an organomagnesium halide, ##STR7## with each mole of an alkyltin trihalide, R.sup.3 SnX.sub.3.sup.2 wherein X.sup.1 and X.sup.2 are individually selected from the group consisting of chlorine and bromine and R.sup.3 is phenyl or a linear hydrocarbon group containing from 1 to 8 carbon atoms;
- 2.
