Application

Bulky phosphine ligand used in a palladium-catalyzed cross-coupling of aminoethyltrifluoroborates with electron-poor aryl bromides.

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.

    A set of phenethylamines has been successfully prepared via Suzuki-Miyaura cross-coupling of diverse potassium beta-aminoethyltrifluoroborates with aryl halides. The potassium beta-aminoethyltrifluoroborates were easily prepared via hydroboration of enamine and enamide precursors. [reaction: see text].

    High-throughput experimentation (HTE) methods are central to modern medicinal chemistry. While many HTE approaches to C-N and Csp2 -Csp2 bonds are available, options for Csp2 -Csp3 bonds are limited. We report here how the adaptation of nickel-catalyzed cross-electrophile coupling of

    Palladium-catalyzed amination reactions of aryl halides have undergone rapid development in the last 12 years, largely driven by the implementation of new classes of ligands. Biaryl phosphanes have proven to provide especially active catalysts in this context. This Review discusses
