Reactions of two intermediate vinylcyclopropylidenes, generated from the corresponding nitrosoureas by two different routes, have been studied.For one of them, a carbene-carbene rearangement was the main reaction mode while for the other, ring opening to the allene occured exclusively.On the other hand, dienyl ethers were the only products from ring-opening of the corresponding cyclopropane diazonium ions formed in methanol under acid conditions.The results of the former reactions relate well to those obtained from treatment of the corresponding gem-dibromocyclopropanes with methyllithium.
