Title:
芳香族化合物の製造方法
Document Type and Number:
Japanese Patent JP7088690
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve such problems that the replacement of a nitro group with a hydrogen atom in production of an aromatic compound requires two-type reactions different from each other comprising reduction to an amino group and conversion of diazonium salt, and those procedures contain such problems that many processes are required and it takes time in production in view of convenience in aftertreatment of reaction and refining operation; and further, a careful handling is required regarding the diazonium salt because that salt is unstable depending on the type of compound and is an intermediate having sometimes the risk of explosion.SOLUTION: There is provided an aromatic compound production method characterized by including: reacting an aromatic nitro compound with a proton supply compound under the presence of a metal catalyst; and directly reducing the nitro group of the aromatic nitro compound to a hydrogen atom.SELECTED DRAWING: None
