Diverse copper(iii) trifluoromethyl complexes with mono-, bi- and tridentate ligands and their versatile reactivity

Cu(iii) trifluoromethyl complexes are proposed as essential intermediates for many copper-promoted trifluoromethylation reactions, but remain elusive and scarcely explored. We report herein the isolation and spectroscopic and X-ray crystallographic charac

Copper-mediated trifluoromethylation using phenyl trifluoromethyl sulfoxide

A new method for the generation of trifluoromethylcopper ( CuCF3 ) species from readily available phenyl trifluoromethyl sulfoxide has been developed. The CuCF3 reagent can be applied in efficient trifluoromethylations of aryl iodides and activated aryl bromides in the absence of additional ligands. Furthermore, the CuCF3 species can also undergo oxidative cross-coupling with terminal alkynes and arylboronic acids.

Controlled trifluoromethylation reactions of alkynes through visible-light photoredox catalysis

The control of a reaction that can form multiple products is a highly attractive and challenging concept in synthetic chemistry. A set of valuable CF3-containing molecules, namely trifluoromethylated alkenyl iodides, alkenes, and alkynes, were selectively generated from alkynes and CF 3I by environmentally benign and efficient visible-light photoredox catalysis. Subtle differences in the combination of catalyst, base, and solvent enabled the control of reactivity and selectivity for the reaction between an alkyne and CF3I. Variety through selectivity: Highly valuable trifluoromethylated alkenyl iodides, alkenes, and alkynes were selectively generated from alkynes and CF3I by environmentally benign and efficient visible-light photoredox catalysis. A suitable choice of catalyst, base, and solvent was crucial for the reactivity and selectivity of these processes.
