Participants

Reaction Steps

A mixture of 20.0 g. of 4-triethylsilyloxymethyl-4-trimethylsiloxy-1-octyne, 18.18 g. of tri-n-butylstannane and 70 mg. of azobisisobutyronitrile is stirred under argon and placed in a bath at 100° C. After 5 minutes an exotherm ensues. The mixture is heated at 130°-140° C. for one hour and then the excess tri-n-butylstannane is removed at 130° C. and reduced pressure. The residue is distilled at 130°-140° C., 0.03 mm. in a Kugelrohr apparatus, giving the desired product as a colorless liquid.
