Paragraph 0060; 0063; 0064, (2018/04/10)
PROBLEM TO BE SOLVED: To provide a method for producing trifluoromethyl group-containing alcohols useful as synthetic intermediates for medicines and agrochemicals. SOLUTION: This invention relates to a method for producing trifluoromethyl group-containing alcohols expressed by a formula (2), comprising: making carbonyl compounds expressed by a formula (1) react with trifluoromethane in an organic solvent in the presence of polyvalent ethers and potassium tert-butoxide, or kalium hexamethyldisilazide. (R1 and R2 are each independently a phenyl group etc.; R2 may combine with R1, to form a ring, and both R1 and R2 are not hydrogen atoms). SELECTED DRAWING: None COPYRIGHT: (C)2018,JPOandINPIT

The Ruppert-Prakash reagent is the most powerful and well-documented reagent for trifluoromethylation. Despite its versatility, no general method exists for its use in a flow system. Here we report the first flow trifluoromethylation of carbonyl compounds

The solvolysis rates of 1-(substituted phenyl)-1-phenyl-2,2,2-trifluoroethyl and 1,1-bis(substituted phenyl)-2,2,2-trifluoroethyl tosylates or bromides were conductimetrically measured at 25.0 °C in 80% aqueous ethanol. The substituent effects on these so
