Name is trans-Cyclohexane-1,2-diamine, as a common heterocyclic compound, it belongs to chiral-catalyst compound, and cas is 1121-22-8, its synthesis route is as follows.,1121-22-8
It was synthesized from 101.2 mg (62.3 mumol) of the [{RuCl2(dppb)}2-mu-(dppb)] [17] and 15.9 mg (129.2 mumol) of the cis and trans (+-) 1,2-diaminocyclohexane (cydn) in toluene (20 mL) under argon atmosphere. The solution was stirred for 5 h at 30 C and then the volume was reduced under vacuum to 3 mL and diethyl ether (10 mL) was added to obtain a yellow powder. The product was thoroughly washed with diethyl ether (3 * 5 mL). The yield was 96.0 mg (95%). Anal. calc. (found) for C34H42N2Cl2P2Ru: C, 61.19% (60.73); H, 6.26% (6.05); N, 3.48% (3.40); 31P{1H}-NMR (202.46 MHz, CH2Cl2/D2O): delta 45.19 (singlet, dppb), CV (TBAH, 0.1 mol L-1 CH2Cl2, 25 C, scan rate = 0.1 V s-1): Epa = 0.52 V, Epc = 0.40 V, E? = 0.46 V, |Ipa/Ipc| = 1.10. IR {KBr, 1 cm-1}: 3331, 3257 and 3054 (weak, nuN-H), 2931 and 2855 (weak,nualkyl-H), 1988, 1895, 1831, 1744 (very weak, harmonic), 1562 (medium, delta NH2def.), 1482 and 1433 (medium, nuarom.), 1093 and 1023 (strong, nuC-N), 896 and 743(strong, tau NH2), 695 and 512 (very strong, nuRu-P), 290 (medium, nu Ru-Cl). UV/vis (see Fig. 1S) (CH2Cl2, 1.27 104 mol L1), l/nm (epsilon/Lmol1cm1) 322 (4728), 456 (407).
With the complex challenges of chemical substances, we look forward to future research findings about trans-Cyclohexane-1,2-diamine
