2-(TRIMETHYLSILYLOXY)FURAN synthesis
- Product Name:2-(TRIMETHYLSILYLOXY)FURAN
- CAS Number:61550-02-5
- Molecular formula:C7H12O2Si
- Molecular Weight:156.25
Yield: 88%
Reaction Conditions:
with triethylamine in dichloromethane at 0 - 20;Inert atmosphere;
Steps:
(furan-2-yloxy)trimethylsilane (2)
To a solution of 2(5H)-furanone (16.9 mL, 238 mmol, 1.0 eq.) in DCM (170 mL, 1.4 M) at 0 °Cwas added triethylamine (33.7 mL, 285 mmol, 1.2 eq.). Then chlorotrimethylsilane (37.4 mL, 250 mmol, 1.05 eq.) was added dropwise to the resulting red brown solution at the same temperature. The suspension was stirred overnight at room temperature. The reaction was diluted with 100 mL pentane and filtered through a frit funnel into a second flask containing 100 mL pentane. The solution was filtered again then concentrated under reduced pressure to give a red brown oil. (If precipitation formed during concentration, immediately dilute it with pentane and filter the solution again.) The crude product was distilled under vacuum (ca. 100 mbar, 105 °C oil bath) to furnish 2 (32.6 g) as a colorless oil in 88% yield.
