WIPO Patent Application WO/2021/018157
Kind Code:
A1
Abstract:
Disclosed are a mixed-ligand nickel(II) complex containing bisoxazoline-derived nitrogen heterocyclic carbene ligand and phosphite ligand and application thereof; the chemical formula of the mixed-ligand nickel(II) complex is Ni(NHC)[P(OR)3]X2, wherein R is one of ethyl and isopropyl, X is one of bromine atom and chlorine atom, and NHC is a nitrogen heterocyclic carbene ligand derived from bisoxazoline. In the presence of magnesium shavings, the mixed-ligand nickel(II) complex containing bisoxazoline-derived nitrogen heterocyclic carbene ligand and phosphite ligand of the present invention can catalyze low-activity chlorinated aromatic hydrocarbons and fluorinated aromatic hydrocarbons with chlorinated benzyl compounds, respectively, reductive cross-coupling reaction at a single temperature, generating a diarylmethane compound in one step, providing a new method for the synthesis of diarylmethane compounds.
