Abstract
N-(thio)carbonyl(thio)amidophosphate, their open-chain and crown-containing analogues with a C (X) NHP (Y) fragments are associated with intermolecular hydrogen bonds as C=X…H-N and P=Y…H-N or intramolecular hydrogen bonds of N-H…O(macrocycle). These compounds easily enter into alkylation reaction, are added according to C=N bonds of activated imines, take part in O → S and S → O exchanging reactions.
