0.592 g (2.79 mmol) of (S,S)-DPEN (MW: 212.3) was introduced into a 50-mL three-necked flask and subjected to argon-gas replacement. 25 mL of dehydrated methylene chloride and 0.41 mL (2.93 mmol) of triethylamine were added and cooled to 0 C. To this solution, a solution consisting of 0.515 g (2.79 mmol) of isohexyl sulfonyl chloride (MW: 184.68) and 25 mL of dehydrated methylene chloride was slowly added dropwise, and stirred at 0 C. for one night. This solution was washed twice with water, then the solvent in the organic layer was distilled away, and dried under reduced pressure to give 1.656 g of a crude product. The crude product was purified by silica-gel column chromatography (silica gel 60N, n-hexane:AcOEt=1:1, then AcOEt 100%) to give 0.306 g of (S,S)-(C2H5)2CHCH2SO2DPEN (30% yield). 1H NMR (400 MHz, CDCl3, rt, delta/ppm): 0.67 (q, J=7.3 Hz, 6H, (C3CH2)2CH), 1.10-1.38 (m, 4H, (CH3C2)2CH), 1.62-1.76 (m, 1H, (CH3CH2)2C), 2.22 (d, J=6.4 Hz, 2H, C2SO2), 4.29 (d, J=5.5 Hz, 1H, C6H5CNH2), 4.56 (d, J=5.5 Hz, 1H, C6H5CNHSO2), 7.15-7.45 (m, 10H, aromatic proton).
29841-69-8, 29841-69-8 (1S,2S)-(-)-1,2-Diphenylethylenediamine 6931238, acatalyst-ligand compound, is more and more widely used in various fields.
