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 104.9 mg (64.6 mmol) of[{RuCl2(dppb)}2-m-(dppb)] [17] and 16.2 mg (141.9 mmol) of the cisand trans (¡À) 1,2-diaminocyclohexane (cydn) in CH2Cl2 (5 mL)under argon atmosphere. The result mixture was stirred for10 min at 30 C, and after that the reaction was stopped withhexane (20 mL), which produced a pale yellow solid. The remainedsolid was filtered off by cannula filtration and washed with hexane(3 10 mL) and dried under vacuum. The yield was 101.7 mg (97%).Anal. calc.
