Reactions with organozirconium compounds

Alkenylation by palladium-catalyzed reactions with organozirconium compounds... 

The simplest reaction of zirconacyclopentadienes is their hydrolysis. It is characteristic for organo-early transition metal compounds the metal—carbon bond is easily hydrolyzed with acids to give free organic compounds. Similarly, deuterolysis of zirconacyclopentadienes, rather than protonolysis, affords deuterated compounds as expected (Eq. 2.9). The position of the deuterium is indicative of the position of the metal—carbon bond in the organozirconium compound. 

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).
