Participants

Reaction Steps

To a stirred solution of 15 g. (0.069 moles) of 4-methyl-4-trimethylsilyloxy-7-oxa-1octyne and 75 mg. of azobisisobutyronitrile is added dropwise, under nitrogen atmosphere, 21.1 g. (0.073 moles) of tri-n-butyltin hydride. The solution is stirred at 130°-135° C. for 11/2 hours, then cooled to ambient temperature. Distillation provides 29 g. (86%) of product as a colorless oil; b.p. 165°-167° C. (0.25 mm.).
