실험 절차

The procedure used for the preparation of 1,3 di(triethoxysilyl) benzene was followed using 1,2 dibromobenzene (100.0 g, 0.424 mg). The product after two distillations was a clear colorless oil (11.9 g, 7%). IR (Neat, CsI, cm-1): 3040 w, 2963 s, 2920 s, 2880 s, 730 w, 1480 w, 1436 m, 1426 w, 1310 w, 1290 w, 1160 s, 1100 vs, 955 s, 780 s, 755 s, 718 m, 700 m, 668 w, 515 m, 484 m. 1H NMR (benzene-d6, 22° C., 300 MHz ): δ 1.21 (t, J=7.2 Hz, 18 H, OCH2CH3), 3.91 (q, J=7.2 Hz, 12H, OCH2CH3), 7.29 (dd, J=5.7 Hz, 2H, C6H4), 8.12 (dd, J=5.7 Hz, 2H, C6H4). 13C{:H} NMR (benzene-d6, 22° C., 75.5 MHz ): δ 18.44 (OCH2CH3), 58.87 (OCH2CH3), 129.25, 137.19, 138.97 (C6H4).
