Abstract Potentiometric titration in nitromethane, IR-and NMR-spectroscopy were used to study the processes of protonation and H-bonding for a number of phosphoric, phosphonic and phosphinic acid amides.[(R½ N) n P (O) R3-n 2 (R1= Me, Et; R2= EtO, Me, Et; n= 1–3) including 1, 3, 2-dioxa-, 1, 3, 2-oxazaphospholane and phosphorinane derivatives.] It was shown that in these compounds the center of the highest basicity is the oxygen of the ...
