The carbon-13 and phosphorus-31 nuclear magnetic resonance spectra of some tertiary phosphines

Abstract

The ³¹P and ¹³C n.m.r. spectra for some tertiary phosphines are reported. Factors affecting the chemical shifts and coupling constants are examined, and it is suggested that the major factor involved in determining changes in chemical shifts from one tertiary phosphine to another is the bond angle at the nucleus concerned.
