Abstract

Keun-Tae Huh, Akihiro Orita, and Howard Alper' ... Department of Chemistry, University of Ottawa, 10 Marie Curie, Ottawa, Ontario, Canada KIN 6N5 ... Summary: The cationic palladium(I1) aquo hydride, trans-(Cy3P)zPd(H)(H20)+BF,-, is an excellent catalyst for the carbonylation of alkynols to dienoic acids and esters and of alkynediols to cross-conjugated diesters. ... Propargylic alcohols, in which the hydroxyl and alkyne units are attached to the same carbon atom, ...
