Synthesis of dienoic acids and esters by cationic palladium complex catalyzed carbonylation of alkynols and alkynediols
摘要:
The cationic palladium(II) aquo hydride, trans-(Cy3P)2Pd(H)(H2O)+BF4-, is an excellent catalyst for the carbonylation of alkynols to dienoic acids and esters and of alkynediols to cross-conjugated diesters.
