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.
