| titleOfInvention | A METHOD TO PREPARE SUBSTANTIALLY PURE ASYMMETRIC TRIORGANOESTANE HALIDES WITH HIGH YIELDS. |
| abstract | A method of preparing in high yields substantially pure asymmetric triorganotin halides of the formula RnR'(3-n) SnX, wherein R represents a linear aliphatic hydrocarbon monovalent radical containing up to six carbon atoms, R' represents a hydrocarbon monovalent radical aliphatic or cycloaliphatic containing up to eight carbon atoms, with the stipulation that the molecular weight of R'exceeds that of R by at least 42 grams per mole except when R' is a cycloaliphatic hydrocarbon radical, X represents an atom of chlorine or bromine, and n is an integer selected from 1 and 2, said method comprising; reacting substantially equimolar amounts of a tetraorganostannic compound R (n + l) R'(3-n) Sn and a stannic tetrahalide SnX4, adding a suitable solvent to dissolve the RSnX3 by-product, and isolating the triorganotin halide in substantially pure form.
