small degree of bondfission. Reactions of 2,4-dinitrophenyl diphenylphosphinothioate (2a) with alicyclic secondary amines result in a good linear Brønsted-type plot with βnuc = 0.52, implying that the reactions proceed through a concerted mechanism. The βnuc value determined for the reactions of 2a is slightly larger than that reported for the corresponding reactions of 2,4-dinitrophenyl diphenylphosphinate

Abstract The synthesis, physical, chemical and spectroscopic properties of eight different types of phosphinous-, phosphinic- and thiophosphinic amides are reported. It is shown that the 31P-chem. shifts of tertiary amides are at lower magnetic field than that of secondary amides. As an exception, in the bis(tertiary butyl) series this trend is reversed.
