Convenient method for the synthesis of phthalazinones via carbonylation of 2-bromobenzaldehyde using Co2(CO)8 as a CO source

Suresh, A. Sivalingam,Baburajan, Poongavanam,Ahmed, Mansur

, p. 3482 - 3485 (2014/06/10)

A simple one-pot synthesis of phthalazinones by the condensation and intra-molecular carbonylative cyclization of 2-bromobenzaldehydes with hydrazines is reported. This method utilizes solid Co2(CO) 8 as carbonyl source making it rea
