3‐dipolar cycloadditions, with either benzyl azide or ethyldiazoacetate, compared to conventional dibenzocyclooctyne (DIBO). In addition, FDIBOs showed unique trackable properties owing to the high NMR sensitivity of the naturally abundant 19F isotope. Biological molecules, including a monosaccharide, a peptide, and a protein, were tested with FDIBOs, and these reactions could be easily monitored by 19F NMR

Although metal-free cycloadditions of cyclooctynes and azides to give stable 1,2,3-triazoles have found wide utility in chemical biology and material sciences, there is an urgent need for faster and more versatile bioorthogonal reactions. We have found that nitrile oxides and diazocarbonyl derivatives undergo facile1,3-dipolarcycloadditions with cyclooctynes. Cycloadditions with diazocarbonyl derivatives
