Palladium-iminophosphine-catalysed carbostannylation of arynes: synthesis of ortho-substituted arylstannanes.
Arynes were found to insert into a carbon-tin bond of alkynyl- and vinylstannanes in the presence of a catalytic amount of a palladium-iminophosphine complex to afford ortho-substituted arylstannanes, which were convertible into a wide variety of 1,2-disubstituted arenes via carbon-carbon bond forming reactions.
