Compound 2 (0.0755 g, 0.0882 mmol) and dppf (0.0492 g, 0.0887 mmol) was suspended in acetone (10.0 mL) and refluxed for 3 h. The solution was filtered by gravity, the filtrate reduced and cold hexane added to yield a solid. The solid was collected by suction filtration and dried in vacuo. 5: yield: 0.0972 g (78percent) of orange powder, mp 200.0¡ãC (dec. without melting). 1H NMR (399.95 MHz, DMSO-d6): delta (ppm)=8.19 (d, 4JHP=4.03 Hz, 2H, HC=N); 7.47?7.87 (m, 20H, PPh2); 6.74 (s, 4H, NH2); 5.18 (br s, 4H, 2¡Á C5H4(dppf)); 5.07 (br s, 4H, 2¡Á C5H4); 4.87 (br s, 4H, 2¡Á C5H4(dppf)); 4.51 (br s, 4H, 2¡Á C5H4); 4.14 (s, 10H, 2¡Á C5H5). 13C NMR (100.65 MHz, DMSO-d6): delta (ppm)=171.5; 152.5; 134.4; 132.8; 131.5; 131.2; 131.0; 128.1; 76.2; 75.8; 73.7; 72.8; 71.4; 69.2. 31P NMR (162.00 MHz, DMSO-d6): delta (ppm)=22.2. FT-IR (KBr, cm?1): nu=3467 (m, N?H); 1602 (w, C=N); 1587 (w, C=N). Elemental analysis for C58H52Cl2Fe3N6Pd2P2S2: found C 49.8, H 4.03, N 5.29, S 4.38percent; calculated C 49.4, H 3.72, N 5.96, S 4.55percent. MS-ESI+: m/z 669 ([M?2Cl]2+, 70percent).
12150-46-8, The synthetic route of 12150-46-8 has been constantly updated, and we look forward to future research findings.
