Synthesis of Hydroxyaryl-aliphatic and (Hetero)aryl Ketones by Acylation of Organometallic Reagents

Diverse hydroxyarylcarboxylic acids afford stable N- (hydroxyaroyl)benzotriazoles which react with heteroaryl, alkyl and aryl Grignard or lithium reagents to give the corresponding hydroxyaryl ketones in 51−94% yields. N- (hydroxyaroyl)benzotriazoles, Grignard, Lithium, hydroxyaryl ketones
