The use of cobalt-rhodium (Co2Rh2) heterobimetallic nanoparticles in the cyclohydrocarbonylation of substituted alkynes and tandem cyclohydrocarbonylation-CO insertion of α-keto alkynes to give 2(3H)- or 2(5/7)-furanones is described
Chemo- and regioselective cyclohydrocarbonylation of α-keto alkynes catalyzed by a zwitterionic rhodium complex and triphenyl phosphite
Van den Hoven,El Ali,Alper
, p. 4131 - 4137 (2007/10/03)
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 triphenyl phosphite affording eith
THE MUKAIYAMA REACTION OF KETENE BIS(TRIMETHYLSILYL)ACETALS WITH α-HALO ACETALS - A CONVENIENT BUTENOLIDE SYNTHESIS
Demnitz, F. W. J.
, p. 6109 - 6112 (2007/10/02)
Ketene bis(trimethylsilyl) acetals were reacted with α-halo acetals giving β-alkoxy-γ-halo acids which were converted to butenolides by reaction with equivalents of base.This constitutes a novel and short butenolide synthesis.
