Abstract
The review is devoted exclusively to the catalyst development and engineering approaches for the one-pot transformation of benzene to aniline. The authors begin with a brief description of the present industrial methods of aniline production and its potential drawbacks regarding the economics and environmental issues. This comprehensive review has been categorized into several sections based on the nature of the catalysts, catalysts preparations and characterizations, their performance and optimizations for aniline yields and selectivity, nature of the aminating agents, and nature of the oxidative agents. Special emphasis has been given to the M/MO cataloreactants, metal redox catalysts, and mesoporous crystalline materials.
