N2 - The inverse-electron-demand Diels–Alder/pyridazine elimination tandem reaction, in which the allylic substituent on trans-cyclooctene is eliminated following reaction with tetrazines, is gaining interest as a versatile bioorthogonal process. One potential shortcoming of such currently used reactions is their propensity to proceed faster and more efficiently at lower pH, a feature caused by the nature of the tetrazines used. Here, we present aminoethyl-substituted tetrazines as the first pH-independent reagents showing invariably fast elimination kinetics at all biologically relevant pH values.
