Abstract

An efficient palladium-catalyzed addition of arylboronic acids to aliphatic nitriles provides a broad range of alkyl aryl ketones in good yields. It is noteworthy that sequential addition and intramolecular annulation reactions of 2-(2-hydroxyphenyl)acetonitriles with arylboronic acids smoothly afford 2-arylbenzofurans in good yields under the standard conditions.
