Reaction Steps
The 2-(2-thienyl)-naphthalene was prepared in the same manner as for the 1-thienyl-naphthalene derivative, with the Grignard being added to 2-bromonaphthalene (2.07 g, 0.01 m). After workup, a brown solid (2.39 g) was isolated. Column chromatography yielded 2-bromonaphthalene (630 mg) and a white crystalline solid (1.13 g, 73% yield based on recovered starting material); m.p. 103°-104° C.; m/z 210 (M+); (Found: C, 79.75; H, 4,80; S, 15.09. C14H10S requires C, 80.0; H, 4.76; S, 15.24); H NMR (CDCl3); δ7.17 (dd, J=5.6, 3.5 Hz, 1H), δ7.30 (dd, J=<1, 5.6 Hz, 1H), δ7.42 (dd, J=<1, 5 Hz 1H), δ7.45 (dd, J=<1, 7 Hz, 1H), δ7.46 (dd, J=1, 4.0 Hz, 1H), δ 7.73 (dd, J=1, 8.0 Hz, 1H), δ7.79 (dd, J=1, 8 Hz, 1H), δ7.81 (s, 1H), δ7.83 (s, 1H), δ5.803 (d, <1, Hz, 1H).
