title: Controllable Mono-/Dialkenylation of Benzyl Thioethers through Rh-Catalyzed Aryl C-H Activation.
abstract: Under solvent control: Benzyl thioethers were alkenylated in excellent yields with broad substrate scope and the selectivity (mono- vs. disubstituted product) was controlled by the solvent and ratio of reactants. Sequential alkenylation with two different alkenes was also carried out in a one-pot process. In addition, the thioether directing group was removed in a one-pot process with simultaneous hydrogenation of the double bond to give the toluene derivatives.
