Chemical reaction rate constants of the nucleophilic ortho-positronium (o-Ps) atom with a series of tetrazine derivatives were determined in dimethylformamide (DMF) solutions by positron annihilation lifetime spectroscopy. The observed rate constants are in the range that corresponds to that of the diffusion-controlled reactions. It was shown that this pronounced reactivity of tetrazines toward o-Ps
