Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Recommanded Product: 2926-30-9, Which mentioned a new discovery about 2926-30-9
The invention discloses a catalytic synthesis of methylation of quinone catalysis triflurormethoxybenzothiazole method. The aim of the invention is to solve the current three industrial fluoromethylation hydrogen fluoride in the reaction, such as four sulfur fluoride strong corrosion, the use of highly toxic fluorination reagent, using a non-metal catalyst at the same time, avoid the industrial pollution problems in heavy metal of the catalyst, has good prospects for the actual application. Using the most simple and cheap benzoquinone and its derivative as photocatalyst, Langlois reagent-trifluoromethane sulfonic acid sodium (CF 3 SO 2 Na) to three fluorine methyl source, in visible light under mild condition, the reaction of metal-free catalytic three fluoromethylation, and through homestyle fixed bed reactor reached the complete full cycle reaction. Can also be further according to the actual need to have biological activity, of the pharmaceutical active of the three methyl modified organic molecule. The invention synthetic mild conditions, raw material is cheap, low environmental pollution, is favorable for large-scale industrial production, with remarkable economic and social benefit.
