| Abstract: | Derivatives of Halogenated Aldehydes. XVI. Investigations of Chloralammonia N-(1,2,2,2-Tetrachloroethyl)trichloroacetaldimine 8 is formed by heating of chloral-ammonia 2 with thionyl chloride. The reaction of 2 with phosphorus pentachloride in ether leads to a mixture of aldimine 8 , 1,2,2,2-tetrachloroethyl-phosphorodichloridate 5 , N-(1,2,2,2-tetrachloroethyl)-phosphorimidic acid trichloride 6 and N-(1,2,2,2-tetrachloroethyl)-phosphoramidic acid dichloride 7 . From compound 7 , the phosphoramidic acid ester 9 , the substituted phosphoric acid triamide 10 and the N-dichlorophosphoryl trichloroacetaldimine 11 are obtained on treatment with methanol, isopropyl amine or triethyl amine, respectively. Compound 9 is also formed from 6 by reaction with methanol. The data of i. r. spectra are concordant with the assigned structures of the compounds 6–11 . |
