Ionic Liquid-Promoted, Highly Regioselective Heck Arylation of Electron-Rich
Olefins by Aryl Halides. — It is found that in ionic liquid several classes of electron-rich olefins undergo highly regioselective reaction with aryl halides giving α-substituted products essentially exclusively. Acidic hydrolysis of the products resulting
from vinyl ethers provides a convenient route to aryl ketones. In contrast, in DMF or
other molecular solvents mixtures of regioisomers are obtained. — (MO, J.; XU, L.;
