Participants

Reaction Steps

A solution of 40.0 g of 4-triethylsilyloxy-4-methyl-1-heptyne, 180 mg of azobisisobutyronitrile, and 50 ml of tri-n-butyltin hydride is stirred under an argon atmosphere at 130° C. for 2 hours, then allowed to cool to ambient temperature. The excess tin hydride is removed by distillation and the residue purified to provide 63.5 g of the (E)-4-triethylsilyloxy-4-methyl-1-tri-n-butylstannyl-1-heptene (b.p. 160°-88° C. at 0.6 mm).
