We have quantum chemically studied the reactivity, site-, and regioselectivity of the 1,3-dipolar cycloaddition reaction between methyl azide and various allenes, including the archetypal allene propadiene, heteroallenes, and cyclic allenes, using density functional theory (DFT). The 1,3-dipolar cycloaddition reactivity of linear (hetero)allenes decreases as the number of heteroatoms in the allene increases and the formation of the 1,5-adduct is, in all cases, favored over the 1,4-adduct, both effects find their origin fro
