- Synthesis method for 9,9'-disubstituent-3,3'-dicarbazyl
-
The invention discloses a synthesis method for 9,9'-disubstituent-3,3'-dicarbazyl, and belongs to the technical field of the organic chemical synthesis. The method comprises the following steps: using 3-boric acid-9-phenylcarbazole as a raw material, and preparing 9-phenyl-3,3'-dicarbazyl under the catalysis of Pd2(dba)3, triphenylphosphine; and preparing a target object by the 9-phenyl-3,3'-dicarbazyl under the catalysis of PdC12(dppf),X-phos. The synthesis method is capable of adjusting the synthetic route, reducing the production of a by-product, improving the yield and reducing the cost. The yield achieves more than 91%. The synthetic route post-treatment of the synthesis method is simple and effective, and is good for industrial production.
