Nickel-catalyzed oxidativeC(sp2)–H/C(sp3)–H coupling of indoles with toluene derivatives is successfully achieved in the presence of 2-iodobutane as the oxidant. This method allows the selective C-2 benzylation of indoles with toluene derivatives over the alkylation with 2-iodobutane and permits the coupling of diversified indoles via the monochelation assistance. The reaction proceeded through a

uncatalyzed Friedel― Crafts alkylation of indoles using microwave irradiation in water is described. A series of functionalized indole derivatives has been synthesized in very short times with moderate to good yields. The combination of microwave irradiation and superheated water offers significant advantages over conventional methods, such as higher selectivities, simplicity, shorter reaction times, and
