Iridium(III) Catalyzed Z-Selective Allylic Arylation of α-Fluoro But-1-enoic Acid Amides via β-F-Elimination in Water

Fluoride-Catalyzed Cross-Coupling of Silylamides to CF3-Acrylates: Access to Highly Functionalized Trifluoromethylated and Quaternary Fluorinated Molecular Architectures

A direct and simple catalytic coupling of nonfluorinated and fluorinated silylbutenamides with β-CF3 α,β-unsaturated esters mediated by fluoride ion was carried out. The transformation proceeded with excellent yields to afford new, highly functionalized trifluoromethylated and quaternary fluorinated products.

Preparation of Thioaminals in Water

The presence of sulfur-carbon bonds is transversal to several areas of chemistry, e.g., drug discovery, materials, and chemical biology. However, a lack of efficient and sustainable procedures for the preparation of thioaminals, the N,S-analogues of O,O-acetals, contributes to this functional group often being overlooked by the scientific community. In this work is described the formation of thioaminals in water promoted by copper(II) triflate.
