Pd-catalyzed ligand-free Suzuki reaction of β-substituted allylic halides with arylboronic acids in water†
Abstract
The catalyst system consisting of Pd(TFA)2 and KOH allows for a wide range of β-substituted allylic halides to react efficiently with various arylboronic acids in neat water under ligand-free conditions, affording the allylated arenes in high yields with broad functional group tolerance and up to 7.4 × 105 TON and 15 416 h−1 TOF.
