An I 2 -mediated 3+2+1 aerobic cyclization reaction of anilines with alkynes and tertiary amines without any peroxides has been reported. This protocol employed tertiary amines as a C1 building block for the direct synthesis of 2-non, 2-alkyl, and even 2-aryl substituted quinolines via C–N bond cleavage. Differing from the traditional methods, both terminal and internal alkynes were compatible in this metal-free three-component system. It is possible that the 2-vinylbenzenamine species might be produced as one of the active intermediates in this process.
