Catalytic synthesis of phenylhydroxylamine compound

During the catalytic synthesis of phenylhydroxylamine compound, substituted nitrobenzene derivative as main material is reacted inside water or organic in the presence of reductant and selenium as catalyst. The substituting radical R in nitrobenzene derivative may be one or several kinds one electron donoring and/or electron accepting substituting radicals or hydrogen atom. The reductaant may be proton donoring reductant, and the catalyst has molar consumption in 0.1-20 % of substrate. The reacting substrate has molar ratio to the solvent of 1 to 1-100, and the solvent is one or several kinds polar or nonpolar solvent. The reaction time is 0.25-20 hr and the reaction temperature is 10-100 deg.c. The present invention has simple operation, easy-to-obtain material, less reaction steps and high yield.
