Phosphonyl radicals ([R2P[double bond, length as m-dash]O]˙) and their adducts are proposed as intermediates in a number of important chemical and biological processes. Despite the great interest in these species, there are no examples of stable, isolated phosphonyl radicals or their adducts reported in the literature. Here we report the synthesis, EPR and theoretical study of stable, isolable cyclic (alkyl)(amino)carbene (cAAC)-phosphonyl radical adducts, [cAAC-P(O)R2]˙ (R = OPri, Ph).

可分离的环状(烷基)(氨基)卡宾-膦酰基自由基加合物。

在许多重要的化学和生物过程中,提出了膦酰基([R 2 P [双键,长度为m-O] O] 3)及其加合物。尽管对这些物种有极大的兴趣,但文献中没有稳定,分离的膦酰基自由基或其加合物的例子。在这里我们报告了稳定,可分离的环状(烷基)(氨基)卡宾(cAAC)-膦酰基自由基加合物[cAAC-P(O)R2]˙(R = OPri,Ph)的合成,EPR和理论研究。
