Secondary Orbital Interactions Enhance the Reactivity of Alkynes in Diels–Alder Cycloadditions

[Image: see text] We have investigated the inverse electron-demand Diels–Alder reactions of trans-cyclooctene (TCO) and endo-bicyclo[6.1.0]nonyne (BCN) with a 1,2,4,5-tetrazine, a cyclopentadienone, and an ortho-benzoquinone. Tetrazines react significantly faster with TCO compared to BCN because the...
