Abstract
A study is made of the reactions of aryl-β-nitrovinyl ketones with hydrogen chloride, hydrogen bromide, and hydriodic acid. It is shown that reaction leads to cyclization forming substituted isoxazoles, and that with hydrogen bromide and hydriodic acid, cyclization is accompanied by reduction. The action of hydrogen chloride on phenyl-β-nitrovinyl ketone gives 3, 4-dichloro-5-phenylisoxazole, while hydrogen bromide gives 5-phenyl- and 3-bromo-5-phenylisoxazoles, and hydriodic acid 5-phenylisoxazole. Chlorination of 3-chioro-5-phenylisoxazole and bromination of 3-bromo-5-phenyl-isoxazole are methods of synthesizing 3, 4-dichloro- and 3, 4-dibromo-5-phenylisoxazole, respectively. The general equations for the reactions are given.
