Abstract In recent years phosphonylated ketones were considered as valuable intermediates in organic synthesis. In the present work we studied the reaction of cyanoalkylphosphonates 1 with organozinc compounds which led after hydrolysis to the corresponding phosphonylated ketones 2 and 3. The structure of these products was confirmed by IR and NMR (1H, 13C, 31P) spectroscopy.

Carbonyl compounds react with organozinc reagents in the presence of diphenyl phosphite to give the corresponding olefins. A variety of 1,3-dienes and unsaturated esters were obtained in moderate to excellent yields under mild conditions.
