Abstract
Abstract A weak base, CsOAc, promotes Suzuki–Miyaura cross-coupling and related Pd- catalyzed reactions under anhydrous conditions as effectively as stronger bases. Aryl triflates exhibit unusual reaction rates, which are comparable to that of bromoarenes. A neglected six-membered transition-state model was proposed to give alternative insight into the key process of transmetalation.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 ...
