29841-69-8, (1S,2S)-(-)-1,2-Diphenylethylenediamine is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: (1R, 2R)-N-p-styrenesulfonyl-1,2-diphenylethylenediamine was synthesized as follows: 1g of (1R, 2R)-1,2-diphenylethylenediamine (4.71mmol) was dissolved in 20mL of CH2Cl2 in the presence of excessive of triethylamine and cooled to 0C, followed by the slow addition of 5mL of CH2Cl2 solution containing 1g of p-styrenesulfonyl chloride (4.78mmol), and stirred at room temperature overnight. The solution was washed with 5% NaOH aqueous solution, dried with MgSO4, and evaporated under vacuum to remove the solvent. The obtained solid was dissolved in diethyl ether, followed by the addition of 1mL of concentrated HCl (37wt%). The formed white precipitated was filtrated, treated with 5% NaOH aqueous, and then extracted with CH2Cl2 for 3 times. The combined organic phase was washed thoroughly with brine and dried over with MgSO4. The solvent was removed under vacuum and 1.28g of light yellow solid (72% yield) was obtained, which was denoted as V-TsDPEN [11]. 1H NMR (400MHz, DMSO-d6, 298K, TMS): delta6.64-7.38 (m, 14H), 6.64-6.67 (m, 1H), 5.87 (d, 1H, J=16.8Hz), 5.35 (d, 1H, J=11.2Hz), 4.33 (d, 1H, J=7.2Hz), 3.95 (d, 1H, J=6.6Hz) ppm., 29841-69-8
As the paragraph descriping shows that 29841-69-8 is playing an increasingly important role.
