Quantitative evaluation of the influence of physicochemical properties of solvents on the kinetics of formation of phosphorus-containing semicarbazides

, p. 1784 - 1789 (2002)
The kinetics of the reaction of diphenylphosphinic acid hydrazide with phenyl isocyanate in various solvents at 25°C was studied. The results can be quantitatively correlated with the physicochemical characteristics of solvents using the four-parameter Koppel-Palm equation. This relationship allows quantitative analysis of the solvation effects. The decisive influence on the reaction rate is exerted by the basicity and polarity of solvents. The reaction mechanism is discussed, and the possible scheme of solvation is suggested.
General Base Catalysis by Organic Bases of the Reaction of Diphenylphosphinic Hydrazide with Phenyl Isocyanate in Benzene
Yanchuk,Ivanets,Yanchuk
, p. 192 - 196 (2003)
The kinetics of the reaction of diphenylphosphinic hydrazide with phenyl isocyanate in the presence of organic bases in benzene at 25°C were studied. The catalytic activity of the bases correlates with spectroscopic and thermodynamic Taft (pKHB), Koppel-Palm (B), and Gutmann (DN) parameters. A common general base mechanism of the catalysis of semicarbazide formation by bases belonging to different classes of organic compounds is offered and discussed.

A series of phosphorhydrazide (PHA) derivatives with the (X = O,S) P-NHα-NHβ-C (X = O,S) skeleton (1-23) were synthesized and characterized by spectral techniques. A single crystal X-ray study of 4 and 21 provided confirmation of the
KINETICS OF THE REACTIONS OF STERICALLY HINDERED ARYL ISOCYANATES AND ARYL ISOTHIOCYANATES WITH P,P-DIPHENYLPHOSPHINIC HYDRAZIDE IN BENZENE
Yanchuk, N. N.
, p. 1604 - 1608 (2007/10/02)
A quantitative assessment of polar and steric factors in reactions of sterically hindered aryl isocyanates and isothiocyanates with P,P-diphenylphsophinic hydrazide indicates similarity in the influence of substituents in the molecules of aromatic isocyan
