Procedure

To a mixture of 15 ml (0.153 mol) of 1,4-dichloro-2-butyne and 13.6 ml (0.16 mol) of trichlorosilane (boiling point: 31°-32° C.) was added 0.15 ml (10 mmol) of an isopropyl alcohol solution of H2PtCl6.6H2O (0.05 g/ml), followed by heating for 8 hours. Thereafter, the mixture was directly distilled to obtain 37 g of 1,4-dichloro-2-(trichloro)silyl-2-butene. Yield: 94%. Boiling point: 70° C./1 mmHg.
