Abstract

Abstract 13C nuclear magnetic resonance data have been recorded for twenty-two tertiary phosphine sulphides. A discussion of the variation in chemical shifts and 31P−13C coupling constants and a comparison of the data with some analogous phosphine oxides are included. The results are examined with respect to a description of the phosphoryl and thiophosphoryl bonds. The 13C and 1H nmr and infra-red spectra of four gold (I) and aluminium (III) complexes of phosphine sulphides are recorded and commented upon.
