A common heterocyclic compound, 14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II), its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route. 14871-92-2
[(bpy)PdCl2] (0.332 g, 1 mmol) and Tl+L (0.475 g, 1 mmol) in 10 mL of dichloromethane were stirred for 18 h at room temperature. The resulting solution was filtered and evaporated to about 1 mL in volume. Then hexane (10 mL) was added to precipitate as a red-orange solid. The solid was repeatedly washed with diethyl ether (3 ¡Á 10 mL) and dried under vacuum to give the pure complex (0.297 g, 52.31% yield, and 1 mmol). Anal. Calc. (%) for C23H16ClN5O2PdS (568.9752): C, 48.61; H, 2.84; N, 12.32; Found (%): C, 48.59; H, 2.82; N, 12.29. TOF-MS: 532.0060 [M – Cl] +. FT-IR: 2152 (m, NCN) cm-1. 1H NMR (DMSO-d6): delta 7.16-7.20 (m, 2H, H-Ar), 7.49-7.51 (m, 2H, H-Ar), 7.65 (t, 1H, H-5, 3J 7.2), 7.74 (t, 1H, H-5′, 3J 7.2), 7.91-7.99 (m, 4H, H-Ar), 8.34-8.40 (m, 4H, H-Ar), 8.76 (d, 1H, H-6, 3J 7.2), 9.09 (d, 1H, H-6′, 3J 7.2). 13C NMR (DMSO-d6): delta 114.0 (NCN), 119.9, 121.9, 124.0, 125.9, 128.9, 133.1, 137.8, 143.0, 147.0, 149.0, 150.7, 157.9.
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II),its application will become more common.
