Use of Mineral Water as a Co-Catalyst for the Conversion of Toxic Nitro Benzene Derivatives to Aryl Amine Derivatives

A series of toxic nitro compounds were converted to aryl amine derivatives at room temperature in the presence of a hydrogen source such as sodium borohydride and in commercially available mineral water without the need for an organic solvent. A commercial catalyst containing Pd (PdAlO(OH) NPs) was used as the supporting material in the study. However, the amount of catalyst used was reduced by 40% compared to the amounts used previously due to the effect of mineral water. Thanks to the developed environmentally friendly and practical method, 8 different nitro arene compounds were converted to aryl amine derivatives with yields over 95%. The most powerful aspect of the developed method is that it is economical and industrial.
