Stable to 150 °C, the heterocyclic carbene 1 is characterized by the typical reactivity of a nucleophilic carbene. Dihydrotriazole 1 can be prepared by simple thermal decomposition of its methanol adduct. X-ray crystal structure analysis, ab initio calculations, and reactivity studies confirm the nucleophilic carbene character of 1.
