Abstract Heteroarene-substituted vinyl-and allyl-silanes were obtained in good yields by the cross-coupling reaction of either heteroaryl Grignard reagents with halovinyl-and haloallyl- silanes or, alternatively, silyl-and silylmethyl-substituted vinylmetallic reagents with heteroaryl halides in the presence of PdCl 2 (dppb) as a catalyst.
