The C-H activated controlled mono- and di-olefination of arenes in ionic liquids at room temperature.

ABSTRACT: In this study, controlled mono and di-olefination of arenes was first realized at room temperature via the C-H bond activation in ionic liquids, probably due to the positive effects of ionic liquids. It is an energy-saving routes in industrial production without the need for heating equipment. Different catalysts were screened, and it was found that [Ru(p-cymene)Cl₂]₂ generated mono-olefinated products predominantly while [Cp*RhCl₂]₂ selectively gave di-olefinated products. These catalysts ([BMIM]NTf₂ and [BMIM]PF₆) as green and recyclable reaction media are highly efficient under mild conditions. This reaction process can avoid any volatile and environmentally toxic organic solvents, and is much safer without
