Preparation, Structure, and Reactivity of 1,3,4‐Triphenyl‐4,5‐dihydro‐1 H ‐1,2,4‐triazol‐5‐ylidene, a New Stable Carbene

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 nu... View More
