(Chemical Equation Presented) A kinetic study is reported for aminolysis of aryl diphenylphosphinothioates (2a-i). The phosphinothioates 2a-i are less reactive than aryl diphenylphosphinates (1a-i), the oxygen analogues of 2a-i, regardless of the basicity
Organic phosphorus compounds 106.1 a 31P-NMR study of phosphinous-, phosphinic-, and thiophosphinic amides

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.
Cyclic sulphur-nitrogen compounds and phosphorus reagents: Part IV - Reactions of phosphiniminocyclotrisulphurtrinitride, (R) Ph2PN-S3N3 (R = phenyl- and morpholino-) with Ph3P and (OC4H8N) Ph2P: six-membered to eight-membered ring (68) conversions

Triphenylphosphine (A) react slowly with Ph3PN-S3N3 (I) both in CH3CN and C6H6 to produce the known disubstituted eight-membered heterocycle, 1,5-(Ph3PN)2S4N4 (III).The recently reported 1,5-2S4N4 (IV) is obtained in better yield (ca. 70percent) from the reaction between (OC4H8N)Ph2PN-S3N3 (II) and (OC4H8N)Ph2P (B) in acetonitrile.However, reactions in benzene of (I) with (OC4H8N)Ph2P and of (II) with Ph3P afford an inseparable mixture of (III) and (IV).Reaction temperature appears to be critical in these ring transformation reactions.
Cyclic Sulphur-Nitrogen Compounds and Phosphorus Reagents. Part 2. Reactions of Tetrasulphur Tetranitride with (Morpholino)diphenylphosphine. First Observation of the ring Contraction of 1,5-2S4N4 to (OC4H8N)Ph2PNS3N3 in Solution

(Morpholino)diphenylphosphine, unlike PPh3, gives only two new compounds, (OC4H8N)Ph2PNS3N3, (1), and 1,5-2S4N4, (2), on reacting with S4N4.The reaction temperature, solvent, and mole ratio of the reactants are critically important in their
