The high atom-economical and eco-benign nature of hydrogenation reactions make them much more superior to conventional reduction and transfer hydrogenation. Herein, a convenient and highly selective hydrogenation reaction of azoarenes using molecular hydrogen to access diverse hydrazoarenes is reported. The present catalytic method is general and operationally simple, and it operates under exceedingly mild conditions (room temperature and 1 atm of hydrogen pressure). The reusability of catalysts used in this method is also successfully demonstrated.

Paragraph 0006; 0016-0017; 0019; 0020-0027, (2020/07/02)
The invention relates to the field of drug intermediate synthesis, in particular to a synthesis method of iminodibenzyl, which mainly comprises two steps: a reduction reaction and a cyclization reaction. The yield can be improved to 88%-92% through fine control of the reduction reaction and the cyclization reaction, and the synthesis method has great industrial significance and is worthy of further popularization.
