摘要

Pyrolysis of the lithium salt of the tosylhydrazone of 4, 4-dimethyl-6-heptyn-2-one(6b) as the dry salt over a temperature range of 150 to 200" C formed 4, 4-dimethyl-l-hepten-6-yne(8), cis-4, 4-dimethyl-5-hepten-l-yne (9), and trans-4, 4-dimethyl-5-hepten-l-yne (10) with an average acyclic enyne composition of 11.1: 4.9: 84.0. The fourth product component, 1, 5, 5- trimethyl-l, 3-~ yclohexadiene (1 la), was formed in 22-28% relative to the acyclic enyne ...
