Procedure
A mixture of 26 g. of 4-methyl-5-methylene-4-trimethylsilyloxy-1-octyne, 200 mg. of azoisobutyrylnitrile and 41.1 g. of tri-n-butylstannane is stirred under argon in an oil bath at 140° C. The mixture is stirred at 140°-150° C. for one hour under argon, then at 140°-150° C. for 1.5 hours under vacuum to remove excess tri-n-butylstannane. The residue is distilled via a Kugelrohr (150° C., 0.05 mm.) giving the desired product as a colorless liquid.
