Abstract

The invention discloses a half-sandwich ruthenium complex and a preparation method thereof, a preparation method of ligand and a reduction method of a nitrobenzene compound. The structure of the half-sandwich ruthenium complex is shown by formula (A), wherein in the formula (A), R1 and R2 are separately selected from H or C1-C7 alkyl, and X is halogen; preferentially, the C1-C7 alkyl is methyl, ethyl or phenyl, and X is chlorine; more preferentially, R1 is H, R2 is H or C1-C7 hydrocarbyl, and X is chlorine; and most preferentially, R1 is H, R2 is methyl, ethyl or phenyl, and X is chlorine. The half-sandwich ruthenium complex is prepared by an efficient preparation method; the half-sandwich ruthenium complex can efficiently and mildly catalyze a nitrobenzene compound to reduce the nitrobenzene compound into an aniline compound; and moreover, the conditions of the preparation method of ligand in the half-sandwich ruthenium complex are relatively mild, and the yield is relatively high.

Description

technical field

[0001] The invention relates to a ruthenium complex, in particular to a semi-sandwich ruthenium complex, a preparation method thereof, a ligand preparation method and a reduction method of nitrobenzene compounds. Background technique

[0002] The complexes of ruthenium with a semi-sandwich structure have unique chemical stability, excellent optical properties and rich redox properties. A very active field. Coordination compounds of ruthenium with a half-sandwich structure play an important role in photochemistry, organic catalysis, olefin metathesis, electrochemistry, fluorescent ion probes, and gas sensing. Therefore, it is a very important research content to synthesize and explore the application of a series of complexes with semi-sandwich structure ruthenium; but there are still some defects in the existing preparation methods of complexes with semi-sandwich structure ruthenium, such as: longer reaction time, Lower yield etc.
