Rhodium(II)-Catalyzed Cyclization Reactions of Alkynyl-Substituted α-Diazo Ketones
Treatment of several o-alkynyl-substituted α-diazoacetophenone derivatives with rhodium(II) carboxylates results in the formation of substituted indenones.The simplest mechanism accounting for the results involves addition of a rhodium-stabilized carbenoi

CYCLOALKENONE FORMATION BY THE INTRAMOLECULAR ADDITION OF A α-DIAZOKETONE TO AN ACETYLENIC PI-BOND
Treatment of several ortho alkynyl substituted α-diazoacetophenone derivatives with rhodium (II) acetate results in intramolecular addition to the acetylenic pi-bond to give a transient cyclopropene which spontaneously rearranges to a vynil carbene interm
