Abstract We have identified cesium trimethoxy(trifluoromethyl)borate [CsCF3B(OMe)3] as a nucleophilic source for the trifluoromethylation of carbonyl compounds. A differentiating characteristic CsCF3B(OMe)3 is its heightened reactivity in ethereal solvents compared to potassium analogue, which typically employed dimethylformamide. Also, contrast extensively studied Ruppert–Prakash reagent (TMSCF3), does not require addition an exogenous activator. Described herein, we detail synthesis and demonstrate efficacy across various scaffolds, including methyl ketones, isatin derivatives, 1,2-acyclic dicarbonyls.

Cu-catalyzed asymmetric construction of a chiral quaternary center bearing CH3 and CF3 groups was achieved with high to excellent enantioselectivity using our originally developed ligands. The conjugate addition Me3Al β-CF3-substituted enones unsaturated ketoesters proceeded efficiently. use gives optically active furanones in yields enantioselectivities. perfluoroalkyl-substituted enone does not seem be favorable the present reaction.
