Catalyst-free alkanoylation of aromatic rings via arylstannanes. Scope and limitations
摘要:
The reaction of alkanoyl chlorides with arylstannanes in 1,2-dichlorobenzene (180 degrees C) is a simple and direct route for the catalyst-free and regioselective synthesis of tertiary alkyl aryl ketones in good to excellent isolated yields (55-77%). Nevertheless, under similar conditions, reactions carried out with alkanoyl chlorides bearing alpha-hydrogens render only the product of protodestannylation. (C) 2009 Elsevier B. V.
