A novel calcium catalyst was found to efficiently functionalize electron‐rich arenes with secondary and tertiary benzylic, propargylic, and allylic alcohols under very mild reaction conditions. The new catalyst system significantly enlarges the scope of the reaction, which was previously limited except for the few examples with secondary benzylicalcohols.
