title: Synthesis of chromans via [3 + 3] cyclocoupling of phenols with allylic alcohols using a Mo/o-chloranil catalyst system.
abstract: The combination of a molybdenum complex (CpMoCl(CO)(3) or [CpMo(CO)(3)](2)) and o-chloranil was used as a catalyst in the [3 + 3] cyclocoupling of phenols and allylic alcohols under microwave heating conditions. Substituted chromans were selectively obtained in moderate to good isolated yields.
