Synthesis and characterization of Lewis base stabilized mono- and di-organo aluminum radicals

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 Et AlCl, respectively, with KC . Compoun...

Summary: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 Et AlCl, 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.
