Reference of 112-27-6, 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. 112-27-6, name is 2,2′-(Ethane-1,2-diylbis(oxy))diethanol, molecular formula is C6H14O4, The 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.
To a solution of 2, 2?- (ethane-1, 2-diylbis (oxy) ) diethanol (55.0 mL, 410.75 mmol, 3.0 eq. ) in anhydrous THF (200 mL) was added sodium (0.1 g) . The mixture was stirred until Na disappeared and then tert-butyl acrylate (20.0 mL, 137.79 mmol, 1.0 eq. ) was added dropwise. The mixture was stirred overnight and then quenched by HCl solution (20.0 mL, 1N) at 0. THF was removed by rotary evaporation, brine (300 mL) was added and the resulting mixture was extracted with EtOAc (3 × 100 mL) . The organic layers were washed with brine (3 × 300 mL) , dried over anhydrous Na2SO4, filtered and concentrated to afford a colorless oil (30.20 g, 79.0%yield) , which was used without further purification. MS ESI m/z calcd for C13H27O6[M + H]+278.1729, found 278.1730.
