摘要

Several 1, 3'-bicyclopropenyi compounds were prepared by treating 1, 3, 3-trisubstituted cyclopropenes with methyllithium followed by reaction of the lithiate with cyclopropenylium perchlorate derivatives. Thermolysis of a sample of 3-methyl-l-(l-methyl-2, 3-diphenyl-2- cyclopropen-l-yl)-2, 3-diphenylcyclopropene at 120" C produced a mixture of diphenylacetylene and (E)-and (2)-2, 3-diphenyl-2-hexen-4-yne. A reasonable ...
