Abstract


The reaction of o-vanillin A with benzyl bromide B2 in acetone as the solvent and K2CO3 as a base in the presence of tetra-n-butylammonium iodide (TBAI) as catalyst formed benzyl o-vanillin, C. The complete assignments of C using PROTON, APT, DEPT-135, COSY, NOESY, HMQC and HMBC NMR in both CDCl3 and acetone-d6 are discussed, and the coupling constants J are reported in Hertz (Hz).


Keywords

[21] Crystal data for C: C15H14O3, M = 242.26, monoclinic, space group P21/c, a = 13.7203(3), b = 4.6599(10), c = 19.1552(5) Ǻ, b = 97.736(1)°, V = 1213.55(5) Ǻ3, Z = 4, Dc = 1.326 g cm–3, m(Mo–Ka) = 0.092 mm–1, F(000) = 512, T = 297 K, 3905 independent reflections. Data were collected on Bruker SMART APEX2 CCD areadetector using w–scans [27], and the non–hydrogen atoms were refined anisotropically using full matrix least squares based on F2 to give R1 = 0.0514, wR2 = 0.1878 for 2949 independent observed reflections [F2 > 2s (F2), 2q = 31.2°] and 164 parameters. The structure was solved and refined by SHELXTL against F2 [28]. The software was used SHELXTL [28] and PLATON [29]. These data can be obtained free of charge from International Union of Crystallography IUCr ci2177 or The Cambridge Crystallographic Data Centre CCDC 627450.
