Synthesis and characterization of Lewis base stabilized mono- and di-organo aluminum radicals123. Issue 76 (6th September 2017) - Kundu, Subrata
Abstract : Synthesis, structure, EPR and theoretical calculations of cyclic (alkyl)(amino)carbene stabilized mononuclear neutral radicals of aluminum containing mono- and di-organo groups. Abstract : Two cyclic (alkyl)(amino)carbene (cAAC) stabilized mononuclear neutral radicals of aluminum have been synthesized. They contain an ethyl [(cAAC)2 AlClEt (1 )] and as well a diethyl group [(cAAC)2 AlEt2 (2 )], and have been prepared from the reduction of EtAlCl2 and Et2 AlCl, respectively, with KC8 . Compounds1 and2 are monoradicals, which were confirmed by EPR measurements to have the spin located on the carbene carbon of one of the cAAC ligands.
