Chemistry & industry
Applications
Usesα-Diazoacetophenone is used as a precursor to carbenes and carbenoids; reagent for preparation of sulfonium, oxonium, and pyridinium ylides; 1,3 dipole for heterocycle synthesis; reagent for Lewis acid or transition metal-mediated insertion reactions; reagent for cyclopropanation of alkenes and for aromatic annulation.
Preparation methods
PreparationPreparative Methods of α-Diazoacetophenone: an improved method of synthesis of diazo ketones has been recently published, via acylation of the lithium enolate of the ketone with 2,2,2-Trifluoroethyl Trifluoroacetate and subsequent reaction with Methanesulfonyl Azide. [1] Alternatively, acylation of diazomethane with aroyl chlorides in the presence of triethylamine provides a general method for the synthesis of aromatic diazo ketones.[2]
