The EPR Spectrum of Triplet Mesitylphosphinidene: Reassignment and New Assignment

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−1 differ significantly from those reported previously for this intermediate. New magnetic parameters of mesitylphosphinidene are discussed along with the results of DFT calculations. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim
