Preparation method of 1-aryl-1,2-dibromoethane

The invention relates to a preparation method of 1-aryl-1,2-dibromoethane. The preparation method of 1-aryl-1,2-dibromoethane includes the steps: under a nitrogen atmosphere, a solvent, an aryl alkaneand N-bromosuccinimide are added in to a reaction tube in sequence, a dibromination reaction is conducted at 80-120 DEG C for 12-48 hours, then, the dibromination reaction is finished, the solvent isremoved through evaporation, and through column chromatography separation, 1-aryl-1,2-dibromoethane compounds are obtained. According to the preparation method of 1-aryl-1,2-dibromoethane, a synthesis technology is simple, reaction conditions are mild, the yield of 1-aryl-1,2-dibromoethane is high, and thus the preparation method of 1-aryl-1,2-dibromoethane is easy to industrialize.

Synthesis of unsymmetrical pyrazines based on ?±-diazo oxime ethers

Synthesis of unsymmetrically substituted pyrazines has been a challenge. The reactivity of ?±-imino carbenoids derived from ?±-diazo oxime ethers has been exploited for pyrazine synthesis, in which the reaction of ?±-diazo oxime ethers with 2H-azirines provides highly substituted pyrazines in good to excellent yields.
