The addition of di-(trimethylsilyl)phosphite to N,N′-terephthalylidene-alkyl-(or aryl-)amines resulted in 1,4-phenylene-bis-(N-alkylamino- methyl)-phosphonic acids in moderate yields. The stereochemical behavior of such reactions was studied, and NMR studies demonstrated that, for several examples, this reaction led to the exclusive formation of only one diastereomeric form. The investigation of the
