| titleOfInvention | Method for producing difluoromethyl group-containing compound |
| abstract | Disclosed is a difluoromethyl group introduction reaction that is useful as a synthetic intermediate for pharmaceuticals and agricultural chemicals. A carbonyl compound or a malononitrile derivative is converted to phenyl (2,3,4,5-tetramethylphenyl) bromodifluoromethylthiophenium tetrafluoroborate or phenyl (2,3,4,5-tetrahydroborate) in the presence of a base. Tetramethylphenyl) bromodifluoromethylthiophenium trifluoromethanesulfonate reacts The difluoromethyl group containing compound represented by these is obtained. In the formula, R1 represents a hydrogen atom, a methyl group, an ethyl group, a linear, branched or cyclic alkyl group having 3 to 10 carbon atoms, R2 represents a hydrogen atom, a methyl group or an ethyl group, and R3 represents a hydrogen atom. , Methyl group, ethyl group, n-propyl group, iso-propyl group and the like, A represents an oxygen atom or a malononitrile group, and R1, R2 and R3 are not all hydrogen atoms. [Selection figure] None |
