Organozirconium compounds alkenes

Organozirconium compounds also undergo the Pd-catalyzed cross-coupling reaction with acyl halides.h i in the presence of ZnCF, the reaction can be carried out more efficiently. Acykirconium species, which are produced via hydrozirconation of alkynes or alkenes by zirconocene hydrochloride followed by insertion of CO, couple with acyl chlorides to give a-diketones (Scheme 12).
