TL;DR: In this article, the substitution of bromine in the title bromomethylpyranone 2 with phenylhydrazine as well as thiourea, like sodium acetate, brings about substitution of Bromine with bromide.
Abstract: Phenylhydrazine as well as thiourea, like sodium acetate, brings about substitution of bromine in the title bromomethylpyranone 2. The pyranone 2 gives the pyrano fused oxazine 9 with hydroxylamine, pyridiazines 10 and 11, respectively with hydrazine and phenylhydrazine, and thiophene 16 with thioacetamide.
