6913-92-4, An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.6913-92-4, name is 1-Benzyl-3-pyrroline. Here is a downstream synthesis route of the compound 6913-92-4
To a solution of the acetylene (1.1 eq) in 1,2-dichloroethane, was added CO2(CO)8 (1.1 eq) and the mixture was stirred 2 hours at room temperature. A solution of the pyrroline (1 eq) in 1,2-dichloroethane and the additive (dimethylsulfoxide or cyclohexylamine) (3.5 eq) were added and the mixture was heated at 83C for 20 hours. The reaction mixture was filtered through celite and washed with CH2Cl2. The filtrate was concentrated and the crude was purified by flash chromatography. From phenylacetylene (5.0 g, 48.3 mmol), Co2(CO)8 (16.5 g, 48.3 mmol), 1-benzyl-3-pyrroline (7.0 g, 43.9 mmol), dimethylsulfoxide (12.0 g, 153.8 mmol) and 1,2-dichloroethane (200 ml). Purification: silica gel, gradient dichloromethane to dichloromethane:methanol 1%, afforded the product (5.9 g, 46%) as yellow oil. 1H NMR (400 MHz, CDCl3): delta (ppm) 7.72 (m, 2H), 7.65 (d, J=3Hz, 1H), 7.40-7.18 (m, 8H), 3.49-3.63 (AB system, 2H), 3.36 (m, 1H), 3.19 (d, J=9Hz, 1H), 2.94 (m, 1H), 2.83 (d, J=9Hz, 1H), 2.43 (t, J=9Hz, 1 H), 2.37 (t, J=9Hz, 1 H). 13C NMR (75 MHz, CDCl3) delta (ppm) 208.94, 159.74, 143.79, 138.30, 131.47, 128.45, 128.38, 128.34, 128.18, 58.91, 56.79, 55.89, 50.24, 42.58. MS (El+) m/z: 289.14 (M+).
