719-80-2, Ethoxydiphenylphosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
719-80-2, General procedure: To a flame dried two-neck round-bottom flask containing CsF (5.50 equiv.) was added o-silyl aryl triflate (II) (1.00 equiv.) in acetonitrile, followed by addition of phosphorous compound of formula (III) (4.00 equiv.) in acetonitrile under argon atmosphere. The reaction mixture was stirred at room temperature and the progress was monitored by TLC. After completion of the reaction, acetonitrile was removed on rotary evaporator and the crude product was dried under high vacuum and purified by flash silica gel column using a gradient of ethyl acetate-petroleum ether to afford corresponding aryl-phosphorous compounds of formula (I) in good to excellent yields. 2-(trimethylsilyl)phenyl trifluoromethanesulfonate (25 mg, 0.083 mmol), Cesium Fluoride (70 mg, 0.461 mmol), Ethoxydiphenylphosphane (78 mg, 0.33 mmol), Acetonitrile (1 ml): Reaction Time: 16 h; Rf: 0.3 (1:3 EtOAc:Pet Ether); White Solid; 17.5 mg, 75%; 1H NMR (400 MHz, CDCl3, TMS) delta 7.74-7.63 (m, 6H), 7.59-7.51 (m, 3H), 7.50-7.40 (m, 6H); 13C NMR (100 MHz, CDCl3, TMS) delta 132.5 (d, J=104.0 Hz), 132.1 (d, J=10.0 Hz), 131.9 (d, J=2.3 Hz); 128.5 (d, J=12.4 Hz); 31P NMR (162 MHz, CDCl3) delta 29.2; Mass (M+Na)+ 301; Known Compound, Lit.
