Abstract

Two cyclic (alkyl)(amino)carbene (cAAC) stabilized mononuclear neutral radicals of aluminum, (cAAC)2Al(Et)R (cAAC = 1-Dipp-3,3,5,5-tetramethyl-2-pyrrolidinylidene; 1, 2; R = Et, Cl) have been synthesized by reaction of cAAC with EtAlRCl and KC8. Compds. 1 and 2 are monoradicals, which were confirmed by EPR measurements to have the spin located on the carbene carbon of one of the cAAC ligands. on SciFinder(R)
