The target compound was synthesized by Ullmann reaction,Buchwald-Hartwig couling reaction using  2,7-Dibrom-9H-carbazol CAS: 136630-39-2.

Carbazole compounds applied research in the field of photoelectric materials has been involved in organic optoelectronic devices molecular electronic photographic materials solar cell materials color LCD materials and cutting-edge technology fields such as organic optical information recording materials, show a broad application prospect in which small molecules carbazole derivatives in organic electroluminescent material occupies very important position, such as 2,7-Dibrom-9H-carbazol CAS: 136630-39-2 is a promising blue light intermediate .

Using 4,4 '-dibrominated biphenyls as raw materials, 1, 2-dichloroethane as solvent, aluminum salt or iron salt as catalyst, dilute nitric acid as nitrification reagent, 2-nitro-4,4' -dibrominated biphenyls were prepared by nitrification reaction.Then, 2,7-Dibrom-9H-carbazolCAS: 136630-39-2 was obtained by removing 2-nitro-4,4 '-dibromo-biphenyl nitro ring with deoxidizer (one of 2-diphenylphosphone-biphenyl, tri-methyl-phenyl phosphorus or diphenyl2-2-pyridine phosphine) with dichloromethane as solvent.Mild and controllable reaction conditions, low cost, simple operation and high yield.The prepared  2,7-Dibrom-9H-carbazol CAS: 136630-39-2 can be used in organic photoelectric materials, medicine and other 

fields, it’s an important intermediate of carbazole photoelectric materials, medicine and pesticide.
