- REACTIONS OF HETEROCYCLIC CATIONS WITH N-CONTANINING NUCLEOPHILES. 16. STUDY OF THE INTERACTION OF 2,6-DIPHENYLPYRYLIUM PERCHLORATE WITH DIAZOLES
-
The direct interaction of 2,6-diphenylpyrylium perchlorate with pyrazoles and pyrazolones led to the synthesis of 4-azolylpyrylium salts, which readily cleave a molecule of perchloric acid in the case of the N-unsubstituted pyrazolones, being converted to

- PHOSPHORIC, PHOSPHONIC, AND PHOSPHINIC ACID AMIDES AS BASES
-
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. 12N)nP(O)R23-n(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 phosphoryl group.
