Paragraph 0110-0114, (2022/01/08)
The invention discloses a trifluoromethyl reagent as well as a synthesis method and application thereof, wherein the structural formula of the trifluoromethyl reagent is as shown in formula I in the specification. According to the invention, diphenyl trifluoromethylphosphine and iodomethane are used as raw materials, and are heated in an organic solvent to carry out an addition reaction to prepare the trifluoromethylation reagent. The method is simple and convenient in process, high in yield and capable of realizing 10-gram-level large-scale preparation; more importantly, the trifluoromethylation reagent can be used as a free radical and a nucleophilic reagent to be applied to free radical addition reaction and simple nucleophilic addition reaction to prepare different types of trifluoromethylation products, so that the method has important application value.

The organic base methodology exploits an access to generate the "trifluoromethyl anion" for carbonyl, ester, acid halide, epoxide, deuterium donor, and carbon dioxide substrates to afford the trifluoromethylation products with good overall efficiency even in organocatalysis conditions. The NMR analysis of the mixture of fluoroform and P4-base shows no change thereof. However, on addition of electrophiles, the trifluoromethylation products were obtained efficiently.
