Despite the great progress that has been made in noble and non-noble heterogeneous catalysts for the chemo selective hydrogenation of challenging substrates 4-nitrostyrene or 3-nitrostyrene, some of the currently developed catalysts are still facing the relatively high cost, inevitably lost during the recovery process, relative harsh reaction conditions, recycling and separation difficulties, waste generation especially when using high equivalent of other hydrogen sources (NH3• BH3, NaBH4), and the problem of being able to be industrialized and practically applied. But at the same time, with the dramatically increasing demand for amine synthesis, especially the requirements for sustainable environmental and economic performance in recent years, low cost, sustainable, high active, and industrial applicable heterogeneous catalysts are remained to be developed urgently. In addition, in the abovementioned catalysts for hydrogenation 4-nitrostyrene or 3-nitrostyrene, we can get vinyl-benzenamine, or the second product of ethyl-benzenamine with modification of catalyst , however, it is usually more difficult to obtain the high chemo-selective products ethylnitrobenzene and vinyl-benzenamine separately in high yield. So, in this case, whether can we developed the most idealist hydrogenation of 4-nitrostyrene system, in which every single product of 4-VA , 4-ethylbenzenamine (4-EA), and 1-ethyl-4-nitrobenzene (4-ENB) can be obtained selectively and in high yield by changing the process conditions? Undoubtedly, this idealist hydrogenation of the 4-nitrostyrene system, is a very critical, important, and novel breakthrough in the application of chemical synthesis and industrial.
