Abstract
[68985-05-7] C13H8N6O (MW 264.25) InChI = 1S/C13H8N6O/c20-13(18-11-7-3-1-5-9(11)14-16-18)19-12-8-4-2-6-10(12)15-17-19/h1-8H InChIKey = ZXYBIPTYOWWVQD-UHFFFAOYSA-N (alkylation with alcohols, preparation of ureas, amides, and nitriles) Alternate Name: 1,1-carbonylbisbenzotriazole. Physical Data: mp 182–184 °C. Solubility: soluble in THF, CH2Cl2, and most polar solvents. Form Supplied in: white solid. Analysis: 1H NMR (CDCl3) δ 8.25 (d, J = 8.3 Hz, 2H), 8.21 (d, J = 8.3 Hz, 2H), 7.78 (t, J = 8.1 Hz, 2H), 7.62 (t, J = 8.1 Hz, 2H); 13C NMR (CDCl3) δ 145.6, 144.7, 132.4, 130.7, 126.7, 120.8, 113.3. Preparative Method: bis(1H-benzotriazol-1-yl)-methanone is readily prepared in a reaction of benzotriazole with phosgene1 or triphosgene.2 Purification: washing with diethyl ether or recrystallization from benzene. Handling, storage, and Precautions: the material is sensitive to moisture – hydrolysis rate is similar to more common bis(1H-imidazol-1-yl)-methanone.3
