Abstract
The application of thiocyanates and isothiocyanates as convenient and available synthones in the the syntheses of a wide variety of nitrogen- and sulfur-containing organophosphorus compounds with linear, cyclic, bipolar structures has been investigated. Thiocyanates react with organophosphorus reagents depending on the reactivity of the latter via cyano- or thiocyanate-groups substitutions, or addition to C≡N bond. The examples of reactions, including hemolytic routes, have been found and studied. Isothiocyanates can add organophosphorus reagents both to C=N and C=S bonds.
