Stereochemical aspects of the hypophosphorous acid addition to terephthalic schiff bases. Synthesis of new 1,4-phenylene-bis-aminomethane-bis-phosphonous acids

Lewkowski, Jaroslaw,Rybarczyk, Malgorzata

, p. 283 - 287 (2008/09/19)

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
