Resumen:
The reaction of alkanoyl chlorides with arylstannanes in 1,2-dichlorobenzene (180°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 á-hydrogens render only the product of protodestannylation
