A simple and easy-to-use strategy is reported that forms C−C and C−S bonds with a divanadium oxoperoxo catalyst. The reaction works well with various substrates in water under aerobic conditions.
conditions. The reaction seems to progress through iron‐catalyzed self‐condensation of the benzyl TMS ether to the corresponding dibenzylic ether. The use of excess arene relative to benzyl TMS ether produced mono‐benzylated arene (di‐ and tri‐arylmethane products), whereas the use of excess benzyl TMS ether versus arene provided bis‐benzylated arene (polyarylated products) in high yields and regioselectivities
