文摘

Pd-catalyzed Suzuki-Miyaura cross-coupling reaction of aryltosylates with potassium aryl trifluoroborate in the presenceof bulky and electron-rich phosphine ligand is described. Inaddition, a useful chemoselective coupling of an aryl chloridein the presence of a tosyloxy group was demonstrated.
