Popis: Introduction of an amino group at the para position of doubly sterically-hindered aryl azides significantly enhances the reactivity with cyclooctynes. The distortability of the azido group is synergistically enhanced by the para-electron-donating group and two bulky ortho substituents, which increases the HOMO energy level and provoke the steric inhibition of resonance, respectively.
