The chemical activation of nitrous oxide (N2O) typically results in O-atom transfer and the extrusion of N2 gas. In contrast, reactions of N-trimethylsilyl (TMS)-substituted amides with N2O give inorganic or organic azides, with concomitant formation of silanols or siloxanes. N-TMS-substituted amides are also able to induce N–Obondcleavage in N2O-derived dialkylaminodiazotates, generating tetrazene

Potassium azidoaryltrifluoroborates have been prepared from the corresponding haloaryltrifluoroborates in 73-98% yields. Also, we successfully cross-coupled the azido-functionalized organotrifluoroborates and carried out a one-pot sequential cross-coupling/1,3-dipolar cycloaddition and a one-pot cross-coupling/azide reduction process.
