SPECIFICATION Title of the Invention Process for the Preparation of Indoles A process for the preparation of indoles which comprises reacting aniline or a derivative thereof with a 1,2-glycol in the presence of a catalyst comprising silver supported on a carrier having a specific surface area of not less than 10 m2/g.
Abstract:
SPECIFICATION Title of the Invention Process for the Preparation of Indole and Derivatives Thereof A process for the preparation of indole and derivatives thereof wherein an aniline is reacted with a 1,2-glycol in the vapor phase, the liquid phase or a mixed vapor-liquid phase under the influence of a copper-containing catalyst. The present invention makes it possible to prepare indole and derivatives thereof in a single step by using inexpensive compounds as the starting materials.
