Procedure

As in reaction conditions of Example XIX Step 2, to 2.84 mL of toluene, the 0.016 g carbonylchlorohydridebis(tricyclohexylphosphine)ruthenium(II) was added, and the reaction was carried out between the 1-[(1-trimethyl siloxy-1-ethynyl)cyclohexyl]-1,1,3,3-tetramethyl-3-vinyldisilazane obtained in Step 1 and 0.92 g 4-chlorostyrene. Product was separated under the purification conditions of Example XII. The product, 1-[(1-trimethylsiloxy-1-ethynyl)cyclohexyl]-1,1,3,3-tetramethyl-3-[(E)-4-chlorostyryl]disilazane, was obtained with a total yield of 86% pure product in the form of an oily, yellow liquid.
