New explortion of 52409-22-0

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 52409-22-0 is helpful to your research. Reference of 52409-22-0

Reference of 52409-22-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 52409-22-0, molcular formula is C51H42O3Pd2, introducing its new discovery.

A 1 – bromo carbazole preparation method (by machine translation)

The invention discloses a 1 – bromo carbazole preparation method, which belongs to the field of organic chemical synthesis. The present invention provides a 1 – bromo carbazole method specific for the preparation of: in order to O-bromophenyl and neighbouring bromine monoiodo-benzene as raw materials, to uhlmann coupling reaction, to produce an intermediate b – (2 – bromophenyl) amine; the intermediate II – (2 – bromophenyl) amine in arrowhead catalyst under the action of the ring-closure reaction to obtain 1 – bromo carbazole. The method of the invention simple reaction operation, solvent can be recycled, low raw material cost, high yield, help to realize commercial process. In addition, by the method of the present invention prepared 1 – bromo carbazole high purity, can be used for the OLED the photoelectric field, medical, dye, in the field of agricultural chemicals and the like, is an important carbazoles intermediate, it has broad application prospects.
