A palladium-catalyzed regioselectiveactivation of C(sp2)–H and C(sp3)–H bonds of benzamides and carboxamides, followed by coupling with disilanes to afford organosilanes in moderate to high yields, with the aid of 8-aminoquinoline as a directinggroup, is reported. Catalytic C(sp2)–H germanylation of benzamides also proceeds under the same palladiumcatalysis. The reaction tolerates a wide variety
