Abstract


The reaction of Benzyl o-vanillin 1 and o-phenylene diamine 2 in dichloromethane produced new benzimidazole, 3. The complete assignments of 3 were made using 1D and 2D NMR including COSY, HMQC and HMBC NMR in CDCl3 and acetone-d6. The coupling constants J are reported in Hertz, and the differences in the peak splittings using both solvents are discussed.

[34] Crystal data of 3: C21H18N2O2, Mr = 330.37, monoclinic, P21/c, a = 9.54170 (1), b = 18.4590 (3), c = 11.0653 (2) Å, b = 123.814 (1)o, V = 1619.27 (4) Å3, Z = 4, m = 0.088 mm–1, dx = 1.355 g cm–3, F(000) = 696, GOF = 1.062. A total of 54869 reflections were collected and 8446 are unique (Rint = 0.0539), R = 0.0501, wR = 0.1282 for 227 parameters and 8446 reflections (I > 2s (I)). Residual electron density extremes were 0.613 and –0.326 e Å–3. The intensity data was collected at 297 K on SMART APEX2 CCD area–detector diffractometer with graphite–monochromated MoKa radiation (0.71073 Å), q range 2.21 to 37.50o [38]. All absorption corrections were performed by using SADABS the multiscan program [38]. The structure was solved and refined by SHELXTL against F2[39]. The H atoms were refined as riding and the Uiso values were freely refined, they were placed in calculated positions, with C–H = 0.93–0.97 Å and N–H = 0.89 Å. The software was used SHELXTL [39] and PLATON [40]. These data can be obtained free of charge from International Union of Crystallography IUCr cv2101 or The Cambridge Crystallographic Data Centre CCDC 620951.
