INVESTIGATIONS IN THE CHROMONE SERIES. PART XVI. REACTIONS OF CHROMONE DERIVATIVES AND 4-THIOCHROMONE WITH METHYLHYDRAZINE

The transformations of 2-methyl-, 2-ethyl- and 2-phenylchromone and 4-thiochromone, 2-methyl- and 8-methyl-4-thiochromone with methylhydrazine were studied.Two series of pyrazoles, A and B, were obtained.The transformations of methyl- and phenylhydrazine with enamino ketones (chromone transformation products) confirmed the course of transformations of chromone derivatives with methylhydrazine.

STUDIES OF CHROMONE DERIVATIVES. PART XV. REACTIONS OF CHROMONE AND ITS DERIVATIVES WITH METHYLHYDRAZINE

The transformations of chromone, 6-methyl-, 6-nitro-, and 8-methylchromone with methylhydrazine have been studied.Two series of pyrazoles (A and B) were obtained and transformation intermediates have been isolated.The structure of these compounds has been established and the reaction course of chromone and its derivatives with methylhydrazine is proposed.
