n reaction of amidines with diynes is reported herein. This protocol provides highly atom-economical access to fabricate two nitrogen-containingheterocycles in one step with high efficiency and selectivity. Significantly, this reaction represents the first example of using diyne as a one-carbon reaction partner in C–H functionalization. Kinetic isotope effects suggested that the catalytic cycle of
