INVESTIGATION OF THE MECHANISMS OF FORMATION OF HETEROCYCLES BY NMR SPECTROSCOPY

The 13C chemical shifts were obtained for the unstable intermediate products in the reactions of 1,3-diketones R1COCH2COR2 (R1, R2= Me, Et, t-Bu, CF3) with hydrazines NH2NHR3 (R3= H, Me, Ph).The results confirm that they have hydroxypyrazoline, hydrazone, dihydroxypyrazoline, and ketohydroxyhydrazine structures.It was shown that 13C NMR spectroscopy can be used for analysis of the complex nonequilibrium reaction mixtures.
