Mm. Wienk et Raj. Janssen, TRIPLET-STATE DI(CATION RADICALS) OF 1,3-PHENYLENE-BIS(METHYLENE PHOSPHORANE), Synthetic metals, 85(1-3), 1997, pp. 1733-1734
EPR spectroscopy is used to characterize a novel triplet ground state
diradical obtained from oxidation of 1,3-phenylene-bis {[(4-t-butylphe
nyl)methylene]triphenyl phosphorane}.
