Mo-catalyzed Friedel-Crafts alkylation using alkenes under mild condition

Mo-catalyzed hydroarylation of alkenes can be achieved at room temperature. The procedure can perform by using electron rich arenes, and the corresponding product is obtained regioselectively as a mixture of para- and ortho-isomers in good yield. Both aryl alkenes and aliphatic alkenes are available in the procedure. On the other hand, a reaction of allylic acetates gives the corresponding allyl arenes via leaving of acetoxy group.
