The nickel/IPr-catalyzed reaction of aryl 2-pyridyl ethers with propiophenone and
acetophenone derivatives via C–OPy bond cleavage is performed in the presence of t-BuOLi to give mono-α-arylated ketones in moderate yields. The method is suitable
for electron-rich and electron-poor ethers as well as heteroaryl ethers and tolerates
a range of active functional groups.
