6-substituted-3,5(Z)-hexadienyl azidoformates produced a cis and trans mixture. The mechanism was proposed as the loss of nitrogen to form an acyl nitrene, then addition to a double bond to produce an aziridine. Finally the cleavage of the C-C bond generated a vinylazomethine ylide followed by recyclization to a fused 2-pyrroline.
Rhodium(II) acetate-catalyzed reaction of ethyl 2-diazo-3-oxopent-4-enoates: Simple routes to 4-aryl-2-hydroxy-1-naphthoates and β,β-unsaturated esters. The dianion of ethyl 4-(diethylphosphono)acetoacetate as a propionate homoenolate equivalent

Rhodium(II) acetate-catalyzed decomposition of ethyl 2-diazo-3-oxopent-4-enoates results in the formation of either 4-aryl-2-hydroxy-naphthoates or β,γ-unsaturated esters. In the latter transformation, the dianion of 4-(diethylphosphono)acetoacetate functions as a propionate homoenolate equivalent.
