Abstract
This study reports sequential dehydrogenation and transfer oxygenation of 1,2-diarylepoxides by high-valent phenCu(III)(CF3)3 and DMSO to produce 1,2-diketones. The Cu(III)-CF3 compound serves as a CF3 radical source to abstract the hydrogen atom of the epoxide ring. The resulting ether α-carbon radical undergoes ring-opening rearrangement to give a ketone α-carbon radical intermediate, which is oxygenated by DMSO with the release of Me2S. The combination of a Cu(III)-CF3 compound and DMSO may be exploited to develop other novel oxidation reactions.

Abstract
The selective synthesis of (Z)- and (E)-β-fluoro-α,β-unsaturated amides via the palladium-catalyzed aminocarbonylation of 1-fluoro-2,2-diiodovinylarenes is described in the present study. Using {Pd(allyl)Cl}2 as a catalyst and DBU as a base in DMF, the primary product is (Z)-isomers. Conversely, the use of a Xantphos ligand along with {Pd(allyl)Cl}2 and Et3N as the bases in 1,4-dioxane leads to the selective formation of (E)-isomers. Notably, 1-fluoro-2,2-diiodovinylarenes with various substituents on the phenyl ring react with various secondary amines, producing the corresponding (Z)-isomeric amides with a high yield and selectivity. In contrast, (E)-isomeric amides exhibit lower yields and restricted applicability.

Abstract
Cu(III)-CF3 compounds are reported herein as novel coupling reagents to mediate ester synthesis from carboxyl acids and alcohols/phenols. Carboxylic acids are transformed to trifluoromethyl ester and acyl fluoride activated species that interact with each other. The broad substrate scope and late-stage application of this method are demonstrated. This study opens up new opportunities to develop interesting reactions using Cu(III)-CF3 compounds without transferring a CF3 group to the products.

Abstract
Incorporation of fluorine into organic molecules is a well-established strategy in the design of advanced materials, agrochemicals, and pharmaceuticals. Among numerous modern synthetic approaches, functionalization of unsaturated bonds with simultaneous addition of trifluoromethyl group along with other substituents is currently one of the most attractive methods undergoing wide-ranging development. In this review article, we discuss the most significant contributions made in this area during the last decade (2012−2021). The reactions reviewed in this work include chloro-, bromo-, iodo-, fluoro- and cyano-trifluoromethylation of alkenes and alkynes.

Abstract
The construction of carbon-fluorine bonds is an important yet challenging task in organic synthesis. Transition metal-catalyzed/-mediated C-F bond forming processes have recently emerged as a viable strategy and provided access to value-added monofluorinated compounds. A dramatic increase in fluorination methods using inexpensive and earth-abundant copper can be seen in the past decade surpassing those using palladium and silver. This review discusses the recent development of Cu-catalyzed/-mediated formation of C(sp2 )-F and C(sp3 )-F bonds.

Abstract
A highly regioselective copper-catalyzed 1,4-chloro- and bromotrifluoromethylation of 1,3-enynes has been presented for the first time, which affords an efficient transformation to access halo- and CF3-containing tetrasubstituted allene derivatives with good to excellent yield. This protocol is practical and convenient, in which a wide range of functional groups are compatible. Applications of this method for the gram-scale preparation and late-stage functionalization of biologically active molecules are also demonstrated.

Abstract
A novel α,α'-azobis(isobutyronitrile) (AIBN)-induced remote trifluoromethyl-alkynylation of thioalkynes with alkynyl triflones as both the trifluoromethyl and alkyne sources is described. Structurally diverse trifluoromethylated (Z)-enynes can be constructed with full control of regio-, stereo-, and site-selectivity, which serves as a highly selective method for the rapid construction of trifluoromethylated molecules.

A one-pot protocol for the Cu(I)-catalyzed difunctionalization of indolyl ynones has been achieved via trifluoromethylation of alkyne followed by dearomatizing spirocyclization of indoles. This cascade process enables constructing diverse CF3-containing spiro[cyclopentane-1,3'-indole] scaffolds in moderate to excellent yields which have challenging quaternary spirocyclic carbon and tetrasubstituted alkenes.
