The dehydrogenativecoupling of indolines with alcohols catalyzed by an iridium complex has been achieved to afford both N- and C3-alkylated indoles selectively, by simply changing the addition time of a base additive. The iridacycle catalyst plays multiple roles in these reactions, which dehydrogenates both amines and alcohols and catalyzes the coupling reactions. Mechanistic studies reveal that a

A green, simple, and efficient protocol for the selective methylenation via CuCl2/oxygen-mediated CâH (sp3) oxidation and CâN cleavage using tetramethylethylenediamine (TMEDA) as a carbon source has been developed. The reactions were achieved in green solvent water under atmospheric conditions. The protocol exhibited a broad substrate scope including indoles, anilines, pyrroles and 1,3-dicarbonyls. Furthermore, two key intermediates of the reaction were successfully identified and the mechanism was explored.
