A novel pattern of the cleavage and reorganization of CN bond in the multicomponent reaction (MCR) of terminal alkynes or haloalkynes, carbodiimides, and benzynes is achieved for the first time to construct efficiently 2‐aminoaryl alkynyl imines. The selective formation and ring‐opening of the azetine intermediate with the high ring strain is essential for this reaction. Further transformation of
