Procedure
A mixture of 0.125 ml (1.0 mmol) of 1-phenylpropyne, 0.192 ml (1.2 mmol) of triethylsilane, and 8.3 mg (0.01 mmol) of bis(triphenylphosphine)iminium μ-hydridebis(pentacarbonylchromium) was heated in a sealed tube at 100° C. for 16 hours while being stirred. GLC analysis of the reaction mixture revealed that (Z)-β-triethylsilyl-β-methylstyrene and (Z)-α-triethylsilyl-β-methylstyrene were produced in a yield of 86% and 4%, respectively.
