Multinuclear magnetic resonance studies. Part 3. Compounds with phosphorus–oxygen–phosphorus or phosphorus–sulphur–phosphorus bridges

Abstract

Phosphorus-31 and carbon-13 spectra are reported for four compounds containing P–S–P bridges, [R₂P(S)]₂S (R = Me, Prⁱ, Bu^t, or Ph), and two with P–O–P links, Me₂P(X)–O–(Y) PMe₂(X = Y = S; X = O, Y = S). Phosphorus-31 relaxation data are also given for the former compounds. ‘Carbon-13 satellites’ in ³¹P resonance have yielded values for J_PP in some cases.
