Ac2O/Et3N Induced Condensation of o-Hydroxybenzophenone with Phenylacetic Acid: A Study of the Mechanism of Coumarin Formation

Sharma, Indra,Ray, Suprabhat

, p. 374 - 375 (2007/10/02)

The mechanism of coumarin formation from o-hydroxybenzophenone and phenylacetic acid in the presence of Ac2O/Et3N has been investigated.Intermolecular hydrogen bonding of o-hydroxy leads to partial carbonium ion formation thereby facilitating nucleophilic
