Solvent-free and room temperature microwave-assisted direct C7 allylation of indolines via sequential C-H and C-C activation.

A Ru or Rh-catalyzed efficient and atom-economic C7 allylation of indolines with vinylcyclopropanes was developed via sequential C-H and C-C activation. A wide range of substrates were well tolerated to afford the corresponding allylated indolines in high yields and E / Z selectivities under microwave irradiation. The obtained allylated indolines could further undergo transformations to afford various value-added chemicals. Importantly, this reaction proceeded at room temperature under solvent-free conditions.
