摘要: The carbon monoxide adduct of an unhindered and highly reactive CAAC-bound arylborylene, [(CAAC)B(CO)Ar] (CAAC = cyclic (alkyl) (amino)carbene), has been prepared using a transfer reaction from the linear iron borylene complex [(PMe3) (CO)3Fe=BAr]. is source dicoordinate [(CAAC)ArB:] that can be liberated by selective photolytic CO extrusion that, although reactive, sufficiently long-lived to react intermolecularly. Through trapping generated in this manner, we present, among others, first metal-free borylene(I) species containing nitrogen-based donor, as well new boron-containing radical.
