Compounds of the type R'P(X)NEt2 (R'=But, OCH(CF3)2; X=F, OCH(CF3)2, Cl) and ButP(Y)(X)NET2 Y=S, Se; X=F, OCH(CF3)2, Cl) were synthesised and investigated in solution by variable temperature NMR spectroscopy.Barriers to rotation about the P-N bond are essentially determined by steric factors and increase with increasing size of the substituents on the phosphorus atom.
