Abstract
Hydrophosphoryl compounds (HPC) is one of the most important and interesting types of organophosphorus substances. That is why a lot of their reactions are the authorized reactions in organic chemistry (Michaelis-Becker, Pudovik, Abramov and Kabachnic-Fields Reactions). In the presented work we have carried out systematic kinetic and synthetical investigation of mechanisms of the Pudovik, Abramov and Kabachnic-Fields reactions and also the reactivity of HPC in these reactions.
