“…The NMR data are analogous to those previously described. 41 1-(4-Fluorophenyl)-1H-benzotriazole (1b) was prepared from benzotriazole (1.2 g) and 1-fluoro-4-iodobenzene (2.7 g) using the general procedure 1, and was isolated (eluent: 4 : 1 heptane-AcOEt) in 80% yield (1.7 g) as a yellow powder: mp 119 °C; 1 H NMR (CDCl 3 , 300 MHz) 7.27-7.33 (m, 2H), 7.43 (ddd, 1H, J = 8.3, 7.0 and 1.0 Hz), 7.55 (ddd, 1H, J = 8.3, 6.9 and 1.1 Hz), 7.68 (dt, 1H, J = 8.4 and 0.9 Hz), 7.72-7.77 (m, 2H), 8.14 (ddd, 1H, J = 8.3, 1.0 and 0.9 Hz); 13 1-(4-Chlorophenyl)-1H-benzotriazole (1c) was prepared from benzotriazole (1.2 g) and 1-chloro-4-iodobenzene (2.9 g) using the general procedure 1, and was isolated (eluent: 4 : 1 heptane-AcOEt) in 78% yield (1.8 g) as a yellow powder: mp 159 °C; 1 H NMR (CDCl 3 , 300 MHz) 7.46 (ddd, 1H, J = 8.4, 6.9 and 1.0 Hz), 7.55-7.62 (m, 3H), 7.74 (ddd, 1H, J = 8.4, 1.0 and 0.9 Hz), 7.74-7.77 (m, 2H), 8.16 (ddd, 1H, J = 8.4, 1.0 and 0.9 Hz); 13 C{1H} NMR (CDCl 3 , 75 MHz) 110.2 (CH), 120.5 (CH), 124.0 (2CH), 124.7 (CH), 128.6 (CH), 130.1 (2CH), 132.2 (C), 134.5 (C), 135.6 (C), 146.6 (C).
