Low-temperature UV-photolysis of mesitylphosphiranes under highly anaerobic conditions leads to the formation of the triplet mesitylphosphinidene (MesP). The recorded X-band EPR spectrum of triplet MesP and the derived zero-field splitting parameter D=4.116 cm differ significantly from those reported previously for this intermediate. New magnetic parameters of mesitylphosphinidene are discussed along with the results of DFT calculations.
在高度厌氧条件下，间二甲基金属膦叶立德的低温 UV 光解导致三重态间二甲基金属磷烯（MesP）的形成。三重态 MesP 的记录的 X 波段 EPR 谱和得出的零场分裂参数 D=4.116 cm 与先前对此中间体报道的值有显著差异。本文还讨论了间二甲基金属磷烯的新磁学参数以及 DFT 计算的结果。
