Procedure

A mixture of 10.0 g. (36.7 mmoles) of 4-dimethoxymethyl-4-trimethylsiloxy-1-octyne, 12.82 g. (44 mmoles) of tri-n-butylstannyl hydride 100 mg. of azobisisobutyronitrile is heated to 140° C. under argon for 2 hours. The excess hydride is distilled off and the residue is purified by molecular distillation (bath temperature=170°-175° C., 0.2mm.) to give 20.5 g. of the title compound.
