Synthesis and characterization of Lewis base stabilized mono-and di-organo aluminum radicals
Chemical Communications, 2017•pubs.rsc.org
Two cyclic (alkyl)(amino) carbene (cAAC) stabilized mononuclear neutral radicals of
aluminum have been synthesized. They contain an ethyl [(cAAC) 2AlClEt (1)] and as well a
diethyl group [(cAAC) 2AlEt2 (2)], and have been prepared from the reduction of EtAlCl2 and
Et2AlCl, respectively, with KC8. 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.
