The addition of dimethyl phosphite to N,N'-terephthalylidene-alkyl- (or aryl-) amines resulted in new tetramethyl 1,4-phenylene-bis-(N-alkylaminomethyl)-phosphonates in moderate yields. The stereochemical behavior of these reactions was studied by NMR, de

Terephthalic Schiff bases react with hypophosphorous acid to form 1,4-phenylene-bis-N-alkyl-aminomethanephosphonous acids in moderate yields. NMR studies demonstrated that - for several examples-this reaction led to the exclusive formation of only one dia
The stereochemical behavior of terephthalic schiff bases in addition of dialkyl or diaryl phosphites
Lewkowski, Jaroslaw
, p. 179 - 195 (2007/10/03)
Addition of dialkyl (or diaryl) phosphites to N-alkyl terephthalic Schiff bases led exclusively to a meso-form but addition to N-aryl terephthalic Schiff bases depended on the substituent of the aryl group. Semi-empirical calculations were involved to fin
