Abstract
The present invention discloses a method for preparing a phenylboronic acid neopentyl glycol ester. A mixed nickel(II) complex with a formula of Ni[P(OR)][(RNCHCHNR)C]Xis used as a catalyst. The method comprises: in the presence of potassium methoxide, efficiently catalyze a cross coupling reaction between a phenyl chloride and a bis(neopentyl glycolato)-diboron to prepare a phenylboronic acid neopentyl glycol ester. The invention provides the first embodiment of using a mixed nickel(II) complex with phosphonate ester and nitrogen heterocyclic carbene ancillary ligands to catalyze a cross coupling reaction.
