A practical method to access β-trifluoromethyl ketonesfrom readily available propargylicalcohols by visiblelight photocatalysis has been developed. Trifluoromethylation of propargylicalcohols with CF3I in the presence of Ru(bpy)3Cl2 as the photocatalyst followed by double-bond migration/keto-enol tautomerization provides β-trifluoromethyl ketones as the final product.
Boron trihalide-promoted ring-opening reactions of gem-difluorocyclopropyl ketones to give the corresponding β-trifluoromethyl ketones and β-halodifluoromethyl ketones were described. It was found that boron trihalides act as both Lewis acids and nucleophiles and the proximal bond prefers to cleave in this transformation.

The first copper-catalyzed ring-opening electrophilic trifluoromethylation and trifluoromethylthiolation of cyclopropanols to form Csp3–CF3 and Csp3–SCF3 bonds have been realized. These transformations are efficient for the synthesis of β-CF3- and β-SCF3-substituted carbonyl compounds that are otherwise challenging to access. The reaction conditions are mild and tolerate a wide range of functional

A simple method for the synthesis of β-CF3 ketones through copper/silver cocatalyzed oxidative coupling of enol acetates with ICH2CF3 has been developed. Enol acetates were chosen as the source of carbonyl group, giving the β-CF3 ketones in moderate yields. Control experiments imply that a radical process maybe involved in this reaction.
