Room-Temperature Suzuki−Miyaura Couplings in Water Facilitated by Nonionic Amphiphiles
摘要:
Use of a dilute aqueous solution containing a nonionic amphiphile allows efficient Suzuki-Miyaura cross-couplings of arylboronic acids with a wide array of aryl halides and pseudohalides, including sterically hindered and lipophilic substrates, in most cases at room temperature.

Expanding the horizons of ArPPh2: New applications of triarylphosphane ligands are presented. The Pd–L1 and Pd–L2 complexes offer exceptionally high activity in Suzuki–Miyaura cross‐couplings of aryl chlorides. The extremely congested synthesis of tetra‐ortho‐substituted biaryl compounds is achieved for the first time by simply using triarylphosphane ligands.
