Palladium-catalyzed cross-coupling of B-benzyl-9-borabicyclo[3.3.1]nonane to furnish methylene-linked biaryls

[GRAPHICS] Benzylboranes are noticeably uncommon partners within Suzuki-Miyaura coupling reactions. B-Benzyl-9-BBN was successfully coupled to a range of aryl/heteroaryl bromides, chlorides, and triflates to give pharmacologically important methylene-linked biaryl structures. Activated, deactivated, and sterically hindered substrates were successfully coupled in high yield using Pd(PPh3)(4) or Pd(OAc)(2) with SPhos as the catalyst system.
