Patent

CA 2301833

In an advantageous 2-halogenated indan-1-one production process, anilines are transformed into diazonium salts, which are then reacted with acryl compounds to produce 3-phenyl-1-halogenated propionic acid derivatives, and the latter are annulated.

L'invention concerne des 2-halogène indane-1-ones qui s'obtiennent de manière avantageuse par transformation d'anilines en sels de diazonium qui sont à leur tour mis à réagir avec des composés acryliques pour donner lieu à des dérivés de 3-phényle-1-acide halogène propionique, ces derniers étant cyclisés.
