Abstract:Control of chemoselectivity is a special challenge for the reduction of nitroarenes bearing one ormore unsaturated groups. Here, we report a flower-like Rh/α-FeOOH catalyst for the chemoselectivehydrogenation of nitrostyrene to vinylaniline over full conversion, which benefits the new functionalizedaminostyrene because the multisubstituted aminostyrenes are usually commercially unavailable. This catalystdoes not only show desirable selectivity for the vinylanilines, but also exhibits the inertness to various otherreducible groups over wide reaction duration. The catalytic selectivity for the reduction of the nitro grouptowards vinyl group was investigated by the control experiments and FT-IR analysis. We have found that theabundant hydroxyl groups in the α-FeOOH may contribute to the improvement of catalytic activity andselectivity. Furthermore, the catalyst exhibits excellent stability and keeps its catalytic performance even after6 cycles.
