Dialkyl hydrogen phosphites add reversibly to dicyclohexylcarbodiimide, forming N,N'-dicyclohexylformamidines.Similar addition products derived from phenylphophoramidites and diphenylcarbodiimide are converted on heating or on prolonged storage at room temperature into 1-dialkoxyphosphino-1,2,3-triphenylguanidines together with other products; their hydrolysis gives anilidophosphates and diphenylformamidine, and under the action of dithiophosphoric acids they lose both alkyl groups, yielding zwitterionic anilido(formamidinio)phosphonates.

Condensation of phenothiazine with phenyl isocyanide dichloride has given 10-(N'-phenylchloroformimidoyl)phenothiazine, exchange reactions of which with salts of dialkylthio- and dithiophosphoric acids result in rearrangement of the initially formed 10-phenothiazines to 10-thiocarbamoyl>phenothiazines, while reaction with diisopropyl dithiophosphoric acid affords diisopropyl chlorothiophosphate, phenyl isothiocyanate, and phenothiazine. 10-(N'-Phenylethoxyformimidoyl)phenothiazine alkylates dithiophosphoric acid to give 10-(N'-phenylcarbamoyl)phenothiazine, while N2-phenyl-N1,N1-diethyl-(10-phenothiazinyl)formamidine reacts with diisopropyl dithiophosphoric acid, affording the salt N2-phenyl-N1,N1-diethyl-(10-phenothiazinyl)formamidinium O,O-diisopropyl dithiophosphate.
