Notes:
Replacement of chloroform by benzene as an NMR solvent for a series of (thio)phosphonothioamides results in an exceptionally wide range of shifts for the N—CH proton signals, from an upfield shift of approximately 1 ppm to a downfield shift of about 0.1 ppm, depending on the phosphonate esterifying groups, the type of the N-alkyl moiety and whether it is a P=O or a P=S compound. The last factor is believed to operate indirectly by affecting the aggregation state of the compounds in benzene.
