Ivanets L. Research of reactionary ability of hydrazides O,O-diarylthiophosphoric acids in the reaction with phenylisothiocyanate

The thesis is devoted to research of hydrazides' O,O-diarylthyophosphoric acids reactionary ability in the reaction with phenylisothyocyanate. Reactionary ability of hydrazides grows at presence of electronodonor substitutes in molecules. With the increase of temperature and electronodonor properties of reactionary environment the influence of hydrazides' structure on their reactionary ability reduces. Correlations of reaction's constant speed from physical-chemical parameters of environment are set. Specific solvatation of hydrazides by electronodonor compounds promotes their reactionary ability. The mechanism of nucleophilic addition and general based catalysis are offered.
