A bridged two-vial system aminocarbonylation protocol where Mo(CO)6 functions as an external in situ solid source of CO has been developed. For the first time both nitro group containing aryl/heteroaryl iodides and bromides gave good to excellent yields in the Mo(CO)6-mediated and palladium(0)-catalyzed conversion to benzamides, while the identical one-vessel protocol afforded extensive reduction of

A room-temperature Ni-catalyzed reductive method for the coupling of aryl bromides with secondaryalkylbromides has been developed, providing C(sp2)–C(sp3) products in good to excellent yields. Slight modification of this protocol allows efficient coupling of activated aryl chlorides with cyclohexyl bromide and aryl bromides with allylic acetate.
