A novel and an expedient metal- and solvent-free synthesis of a wide variety of 2-benzyl-4-arylquinoline derivatives is described from readily available arylamines, styrene oxides and aryl acetylenes in the presence of 10 mol% molecular iodine. This domino reaction occurs under metal- and solvent-free conditions at 120 °C, which avoids the usage of metal catalyst and as a consequence generation of

Three become one: Multiply substituted quinolines were synthesized from diaryliodoniums, alkynes, and nitriles by a CuII‐catalyzed method. This cascade annulation is highly regioselective, step‐economic, flexible with regard to the functional groups, and could potentially be applied to the synthesis of complex molecules.

An efficientnickel-catalyzed cascade reaction of 2-vinylanilines with gem-dichloroalkenes has been developed to deliver diversely substituted quinolines in good to high yields. This protocol enables effective access to quinolines bearing various functional groups in the cascade process from readily available feedstock chemicals. Mechanistic studies suggest that two plausible pathways are involved
