摘要:
Aminobenzenes (e.g., aniline) are converted to the corresponding hydroxybenzene by reaction with water in the presence of a hydrogen transfer catalyst (e.g., palladium) and a reaction propagating agent selected from cyclohexanones and cyclohexylimines. The cyclohexylimine may be formed by initially adding a reducing agent (e.g., hydrogen) to the aminobenzene.
