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.
