Abstract

Palladium-catalyzed cross-coupling reaction of aryl-or alkenylboronic acids with acid chlorides in the presence of copper (I) thiophene-2-carboxylate (CuTC) as an activator in diethyl ether at room temperature under strictly non-basic conditions affords the diaryl ketones or chalcones in moderate to excellent yields. A wide range of substrates bearing an electron-donating or an electron-withdrawing substituent on the aromatic ring are ...
