Abstract

Ultra-small FeS2 nanoparticles were prepared and used as catalysts in a hydrogen transfer reaction for the synthesis of substituted anilines. The catalytic performance is superior to current systems across all reactions, within the timeframe of two hours (100 % conversion, 99.9 % selectivity and activation energy 26.8 kJ mol1). The superior catalytic performance was consistent across hydrogen transfer reactions with a number of different nitroarene substrates. Ultra-small FeS2 nanocatalyst, with size 3 – 6 nm, were prepared via solvothermal method, utilizing oleylamine as a capping agent and a combination of milder temperature (160 °C) and longer reaction time than those reported to date. Tests on recyclability confirmed that the FeS2 nanocatalyst remains highly chemoselective, up to four cycles.
