Procedure

A mixture of 25.4 g. (0.12 mol) of 3-chloromethyl-2,5-dichloro-4-methylthiophene, 34.6 g. (0.132 mol) of triphenylphosphine and 200 ml. of benzene was heated to the reflux overnight. The resulting beige solid was filtered to yield (2,5-dichloro-4-methyl-3-thenyl)-triphenylphosphonium chloride, m.p. 238°-240° C.
