Electric Literature of 77668-42-9, A common heterocyclic compound, 77668-42-9, name is 2,3-Dichlorobenzoyl cyanide, molecular formula is C8H3Cl2NO, its 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 the reactor was added 40g aminoguanidine carbonate and 200ml of methanol (entrainer)30g concentrated sulfuric acid was added dropwise with stirring, the addition was completed dropwise distillation entrainer,And bring out the water, suction filtration,Solid into the reaction flask, at 80 C under reduced pressure and drained.Adding 2,3-dichlorobenzoyl cyanide solution obtained in step (1), heating to 80 C., reacting for 3 h to the end of the reaction, lowering to room temperature, and filtering by suction to obtain white sand particles;
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
