New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 288-36-8, name is 1H-1,2,3-Triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. name: 1H-1,2,3-Triazole
To a stirred solution of 1,2,3-triazole (2.0 g, 28.9 mmol) in THF (10 mL) was added NaH (1.065g, 43.1 mmol) portion wise at 0 C under inert atmosphere. After being stirred for 45 min at 0 C, 2-(trimethylsilyl)ethoxymethyl-Cl (SEM-C1; 7.6 mL, 43.1 mmol) was added to the reaction mixture. After completion of addition the reaction mixture was allowed to warm to RT and stirred for 12 h. The reaction mixture was quenched with water and extracted with ethyl acetate (2 x 100 mL). The combined organic extracts were washed with brine, dried over anhydrous Na2S04 and concentrated under reduced pressure to give crude compound. The crude material was purified by column chromatography eluting with 10% EtOAc/hexane to afford N-2- (trimethylsilyl)ethoxymethyl-l,2,3-triazole (3.5 g, 17.5 mmol, 61%) as a liquid. Mass: m/z 200 [M++l].
