Abstract
A procedure for preparing phosphorylguanidines of the general formula: **(See formula)** where a cation represents Me and (See formula) represents the rest of a primary or secondary, aliphatic, isocyclic or heterocyclic amine that does not contain any ionogenic group, and R1 and R2 can be linked together to form a heterocycle, whose procedure consists of: a) condensing a guanidine of general formula: **(See formula)** where (See formula) has the same meaning as in formula (I), with a diaralkyl phosphite, in the presence of carbon tetrachloride and an alkali and then subjecting the thus obtained diaralkyloxyphosphorylguanidine to catalytic hydrogenolysis or b) condensing a salt of a primary or secondary amine with a salt of a diaralkyloxyphosphorylated derivative of cyanamide and then subjecting the thus obtained diaralkyloxyphosphorylguanidine to catalytic hydrogenolysis.
