ChemInform Abstract: Gaseous “H3PS2” ‐ Generation and Characterization.

Abstract Collisional activation (CA) mass spectra and thermochemical data show that the alkene elimination from the dialkyldithiophosphinic acids (I) leads to a mixture of the tautomeric radical cations (II) and (III) containing tri‐ or dicoordinated phosphorus, whereas tetracoordinated phosphorus corresponding to the ionized dithiophosphinic acid H 2 P(S)SH is not observed.
