Reference of 92507-97-6, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 92507-97-6 name is 1-ethyl-2,3-dimethylimidazolium chloride, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
3. 1-ethyl-3-methyl-2-methylene imidazoline 5.96 g (37.12 mmol) 1-ethyl-2,3-dimethyl-imidazolium chloride and 2.98 g (74.24 mmol) KH are mixed in a 250 ml flask in a glove box. 100 ml THF is added to the solution, and this is stirred for 60 h at room temperature. The reaction mixture obtained is filtrated over celite, and all components which are volatile at room temperature are condensed from the solution. Subsequently, the product is distilled at 160 C./0.1 mbar in a Schlenk tube cooled with nitrogen. Yield: approx. 70% (colorless liquid extremely sensitive to humidity, which quickly colors yellow under partial decomposition at room temperature). 1H-NMR (C6D6, 200 MHz): delta=0.92 (t, 3H, NCH2CH3), 2.56 (s, 3H, NCH3), 2.65 (s, 2H, CCH2), 3.00 (q, 2H, NCH2CH3), 5.56 (d, 1H, EtNCH), 5.61 (d, 1H, MeNCH). 13C-NMR (C6D6, 50 MHz): delta=12.64 (NCH2CH3), 32.49 (CCH2), 39.82 (NCH3), 40.42 (NCH2CH3), 110.94 (EtNCH), 113.27 (MeNCH), 151.80 (NCN).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-ethyl-2,3-dimethylimidazolium chloride, and friends who are interested can also refer to it.
