Abstract

We report a new in situ borylation method using tetrakis (dimethylamino) diboron, DMA4B2, in the presence of a diol. Our method uses standard borylation conditions and readily available Pd-catalysts. The scope of this method includes aryl halides and triflates as well as vinyl halides and triflates. The method successfully works with a broad range of diols, enabling the selection of the best boronic ester for subsequent Suzuki coupling.
