L. Maier et Pj. Diel, ORGANIC PHOSPHORUS-COMPOUNDS .106. A P-31-NMR STUDY OF PHOSPHINOUS-AMIDES, PHOSPHINIC-AMIDES, AND THIOPHOSPHINIC-AMIDES, Phosphorus, sulfur and silicon and the related elements, 115, 1996, pp. 273-300
The synthesis, physical, chemical and spectroscopic properties of eigh
t different types of phosphinous-, phosphinic- and thiophosphinic amid
es are reported. It is shown that the P-31-chem. shifts of tertiary am
ides are at lower magnetic field than that of secondary amides. As an
exception, in the bis(tertiary butyl) series this trend is reversed.
