Adding a certain compound to certain chemical reactions, such as: 6683-75-6, name is 1,2-Dibromo-4-tert-butylbenzene, belongs to bromides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6683-75-6, name: 1,2-Dibromo-4-tert-butylbenzene

In a three-necked flask equipped with a reflux tube, 292 g (1.0 mol) of p-tert-butyl o-dibromobenzene, 90 g (1.0 mol) of cuprous cyanide, 16.8 g (0.1 mol) of silver carbonate, and 52.4 g of copper acetylacetonate (0.2%) were added. 1460 mL of mol) and DBU were heated to 100 C. After the reaction, the insoluble material was filtered off and the DBU was recovered under reduced pressure. The residue was poured into water and filtered to give 95 g of p-tert-butylphthalonitrile. The yield was 51.6%.

Electric Literature of 6683-75-6,Some common heterocyclic compound, 6683-75-6, name is 1,2-Dibromo-4-tert-butylbenzene, molecular formula is C10H12Br2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

In a three-necked flask equipped with a reflux tube, 292 g (1.0 mol) of p-tert-butyl o-dibromobenzene was added.Potassium ferricyanide 329 g (1.0 mol), DBU 1460 mL, silver carbonate 16.8 g (0.1 mol) and copper acetylacetonate 52.4 g (0.2 mol),The reaction was heated to 100 C. After the reaction was over, insoluble material was filtered off and the DBU was recovered under reduced pressure. The residue was poured into water and filtered to obtain 180 g of p-tert-butylphthalonitrile, with a yield of 97.8% and a purity of 99.0%.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1,2-Dibromo-4-tert-butylbenzene, its application will become more common.
