Visible-Light-Driven Sulfonation of α-Trifluoromethylstyrenes: Access to Densely Functionalized CF3-Substituted Tertiary Alcohol

Reported herein is a visible-light-induced sulfonation of α-trifluoromethylstyrenes with sodium sulfinates, which provides a series of α-trifluoromethyl-β-sulfonyl tertiary alcohols. This new synthetic protocol is enabled by a charge-transfer complex between oxygen and sulfinates, featuring broad substrate scope and scalability. Excellent functional group compatibility and chemoselectivity render this method suitable for sulfonation of pharmaceutically relevant molecules. In the presence of D2O, deuteriotrifluorinated products were also obtained, further demonstrating the flexibility and synthetic potentials of this strategy.

Photoredox/Hydrogen Atom Transfer Cocatalyzed C-H Difluoroallylation of Amides, Ethers, and Alkyl Aldehydes

Herein, we report a method that combines hydrogen atom transfer and photoredox catalysis to achieve the dehydrogenative difluoroallylation of amides, ethers, and alkyl aldehydes. This operationally convenient method transforms a broad scope of substrates into the corresponding gem-difluoroalkenes via the construction of C(sp3)-C(sp3) or C(sp3)-C(sp2) bonds. Excellent functional group compatibility and high selectivity make this method have a wide range of substrate types and render it suitable for late-stage modification of pharmaceutical intermediates.

One-pot synthesis of α-trifluoromethylstyrenes from aryl ketones and the Ruppert–Prakash reagent

A new synthesis of α-trifluoromethylstyrenes from aromatic ketones and (trifluoromethyl) trimethylsilane is described. The reaction involves nucleophilic trifluoromethylation and elimination of trimethylsilanol, which are performed within one reaction fla

Photoredox relay-catalyzedgem-difluoroallylation of alkyl iodides

Herein, a new example of relay catalysis, using a combination of Mn2(CO)10and an iridium-based photocatalyst, is reported. In our relay catalytic reaction, the Mn catalyst and iridium-based photocatalyst catalyze the reaction at different stages in the desired sequence under the same reaction conditions, and do not inhibit each other. This convenient method transforms a broad scope of alkyl iodides into the correspondinggem-difluoroalkenesviaC(sp3)-C(sp3) bond construction. The protocol has good functional group tolerance and is suitable for the late-stage modification of multifunctional complex molecules.
