To a solution of THP ether 1 (1.7 g, 3.3 mmol) in THF (10 mL) was added a 1 M solution of tetrabutylammoniumfluoride in THF (5 mL, 5 mmol) at 22-24oC. The solution was stirredfor 2 h and diluted with 100 mL (1:1) of Et2O/EtOAc solution. Theo...
wetted with methanol (100 mL)) (Note 9) (7 x 4 cm) in a 150 mL medium porosity fritted Büchner funnel into a 1 L round-bottomed flask (24/40 joint) (Figure 2) using methanol (300 mL) as the eluent (Note 10).
(Note 2) via syringe. Then, dry THF (30 mL) (Note 3) is added at 23 °C to the flask via syringe and stirring is started (300 rpm). After one min of stirring, tetrabutylammonium fluoride solution (19 mL, 1.0 M in THF, 19 mmol, 1.2 equiv) (Note 4) is added via syringe ...
unsaturated aldehydes in high regio- and diastereoselectivities under mild conditions is achieved. 4) A highly efficient stereoselective synthesis of (Z)-monofluoroenals from acyclic β-halo-enals in the presence of TBAF in THF under mild conditions is described. In ...

In this work, we studied thenhydrate-based separation of CO2 from flue gas (CO2/N2)nderiving from ammonia plant. With the purpose of easynoperation and low cost, we used thermodynamicnpromotors to decrease the formation pressure of CO2/N2nhydrates. First, the effects of THF, TBAB and TBAF...
Herein we report that tetrabutylammonium fluoride (TBAF) is a very efficient catalyst for the addition of trialkylsilylalkynes to aldehydes, ketones, and trifluoromethyl ketones in THF solvent at room temperature. The reaction conditions are mild and operationally simple, and a variety of aryl ...
摘要: The aldol reaction of β-allenoate with use of a commercial THF solution of tetrabutylammonium fluoride (TBAF) yielded polyfunctionalized (2E,4E)-4-carbinol alkadienoate—a valuable building block—in highly regio- and stereoselective fashion.关键词:...
