Landstrom, Evan B. published the artcileEvanPhos: a ligand for ppm level Pd-catalyzed Suzuki-Miyaura couplings in either organic solvent or water, SDS of cas: 480438-51-5, the publication is Green Chemistry (2018), 20(15), 3436-3443, database is CAplus.
A new biaryl phosphine-containing palladium complex was constructed and its usefulness in Suzuki-Miyaura cross-couplings of functionalized substrates so as to yield biaryls was evaluated. By a combination of pre-activation using DIBAL and employment of uncommon solvent EtOAc, the novel catalyst proved effective with extended bench stability at loadings in the ppm (0.1-0.5 mol%) range with highly functionalized reaction partners. Similar reactions run in water containing nanomicelles were as fast or faster. This methodol. represented an attractive green synthetic advance in highly valued Suzuki-Miyaura couplings.
