CYCLOALKENONE FORMATION BY THE INTRAMOLECULAR ADDITION OF A α-DIAZOKETONE TO AN ACETYLENIC PI-BOND
Padwa, Albert,Krumpe, Keith E.,Zhi, Lin
, p. 2633 - 2636 (1989)
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
Rhodium(II)-Catalyzed Cyclization Reactions of Alkynyl-Substituted α-Diazo Ketones
Padwa, Albert,Krumpe, Keith E.,Gareau, Yves,Chiacchio, Ugo
, p. 2523 - 2530 (2007/10/02)
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
