Reactions of 6-methyl-, 2-methyl- and 2,8-dimethylchromones, as well as of 6-methyl-, 8-methyl- and 2,8-dimethyl-4-thiochromones with phenylhydrazine have been investigated.A lack of reactivity in thiocarbonyl group in 4-thiochromone system has been established.Intermediate products of reactions have been separated, their structure established and the reaction course described.
