Two cyclic (alkyl)(amino)carbene (cAAC) stabilized mononuclear neutral radicals of aluminum have been synthesized. They contain an ethyl [(cAAC)AlClEt (1)] and as well a diethyl group [(cAAC)AlEt (2)], and have been prepared from the reduction of EtAlCl and EtAlCl, respectively, with KC. Compounds 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.
