Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 32993-05-8, C41H35ClP2Ru. A document type is Patent, introducing its new discovery., category: ruthenium-catalysts
The present invention relates to can be used as pharmaceutical intermediates shown in a following formula (III) diaryl-substituted imidazoles synthetic method, said method comprising: in the organic solvent, in catalyst, organic ligand and the presence of acid promoter, the following formula (I) compound, the compound of formula (II) compounds and radical reaction, after-treatment after reaction, so as to obtain the compound of said formula (III), wherein R 1, R 2 each independently selected from H, C 1-C 6 alkyl, C 1-C 6 alkoxy or halogen; X is halogen. The method adopts the specific reaction substrate, and through the catalyst, organic ligand, acidic promoter and organic solvent and in the comprehensive selective, thus can yield to obtain the target product, the imidazole compound of this kind the successful preparation, optimizes a synthesis process, improving the product yield, is very favorable to the large-scale production, has a broad market application prospect.
