合成了两个环状（烷基）（氨基）卡宾（cAAC）稳定的单核中性铝自由基.它们含有乙基[（cAAC）2AlClEt（1）]和二乙基[（cAAC）2AlEt2（2）]，并已分别由EtAlCl 2和Et2AlCl与KCl还原制备。化合物1和2是单价自由基，其通过EPR测量证实具有位于cAAC配体之一的卡宾碳上的自旋。
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.
