p-Nitrophenoxy-acetoneのブロム化に就いて

抄録

Behavior of p-nitrophenoxyacetone against bromination was clarified from the structure of thiazole compounds formed by the condensation of the product of the former reaction with thiourea. Bromination in benzene gives an oily substance of α-bromo compound with concurrent formation of γ-bromo compound of m.p. 102°. Their respective condensation with thiourea give 2-amino-4-methyl-5-p-nitrophenoxythiazole and 2-amino-4-p-nitrophenoxymethylthiazole, respectively. The structures of these thiazole compounds were determined by the formation of their derivatives or their syntheses by other methods.
