| Abstract | α-Keto alkynes react with CO and H2 in the presence of catalytic quantities of the zwitterionic rhodium complex (η6-C6H5BPh3)-Rh+(1,5-COD) and tri-Ph phosphite affording either the 2-, 2(3H)-, or 2(5H)furanones in 61-93% yields. The cyclohydrocarbonylation is readily accomplished using substrates contg. alkyl, aryl, vinyl, and alkoxy groups at the acetylenic terminal, as well as a variety of primary, secondary, and tertiary alkyl, aryl, and heteroaryl groups connected to the ketone functionality. Structural and electronic properties present in the starting materials mediate the chemoand regioselectivity of the reaction. |
