摘要：

The direct arylation of weakly acidic sp(3)-hybridized C-H bonds via deprotonated cross-coupling processes (DCCP) is a challenge. Herein, a palladium(NIXANTPHOS)-based catalyst for the monoarylation of 4-pyridylmethyl 2-aryl ethers to generate diarylated 4-pyridyl methyl ethers is introduced. Furthermore, under similar conditions, the diarylation of 4-pyridyl methyl ethers with aryl bromides has been developed. These methods enable the synthesis of new pyridine derivatives, which are common in medicinally active compounds and have applications in materials science.
