METHOD FOR PRODUCING AMINOCARBAZOLES |
摘要 |
Disclosed is a method for producing an aminocarbazole by catalytically reducing a nitrocarbazole, wherein as a catalyst is used an active nickel-based catalyst prepared by contacting a nickel-based catalyst with an alkali and an iron compound under a hydrogen gas or inert gas atmosphere in an inert solvent, and according to the method of the present inventions decrease in reaction speed, decrease in yield of a product or the like depending upon the lot of the starting nitrocarbazoles can be prevented, and aminocarbazoles can be produced in a good yield constantly.
