R1, R2, and R3 may be the same or different and are a substituent such as a hydrogen atom. R4, R5, R6, and R7 may be the same or different and are a substituent such as a hydrogen atom. X represents a halogen atom. R8 represents a substituent that has a π bond and 3-20 carbon atoms. With regard to the electron-donating properties of R1-R7 with respect to the coordination center M of the ligand containing R1-R7 that is indicated in formula (2), R1-R7 are arranged in combination such that the TEP value obtained from infrared spectroscopy shifts toward the high frequency side compared to the TEP value of the ligand of formula (2-1).

摘要: An aromatic nitro compound has a structure in which a nitro group and a halogen atom, in a separated state, are directly bonded as substituents to the ring structure of the same ring; a reaction composition is provided which, in a hydrogenation reaction of the nitro group of said aromatic nitro compound, allows selectively hydrogenating the nitro group, and sufficiently reducing the separation of the halogen atom from the ring; also provided is a reaction system that uses this reaction composition. This reaction composition includes a catalyst which, with the aforementioned aromatic nitro compound as reactant, is used in a hydrogenation reaction of at least one of the one or more nitro groups of said reactant. Further, the reaction composition includes a base and an organic solvent. The catalyst includes a carrier, and Fe oxide particles and Pt particles supported by the carrier.
