Ruthenium(II)‐catalyzed switchable ortho C−H activation of 1‐arylpyrazoles with maleimides has been achieved. This divergent reaction selectively installs various succinimide and maleimide substituents on the aromatic ring of 1‐arylpyrazoles. Depending on the acidic or basic reaction conditions, a w...

Description
Summary:Ruthenium(II)‐catalyzed switchable ortho C−H activation of 1‐arylpyrazoles with maleimides has been achieved. This divergent reaction selectively installs various succinimide and maleimide substituents on the aromatic ring of 1‐arylpyrazoles. Depending on the acidic or basic reaction conditions, a wide range of alkylation and alkenylation products are obtained, without the formation of bis‐adducts.
