18437-78-0, Tris(4-fluorophenyl)phosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of 0.28 g (0.76 mmol) of iodo aminoester (S)-2-(t-butyloxycarbonylamino)allyl-4-iodobutanoate (III’) and 0.48 g (1.5 mmol) of [tri-(4- fluorophenyl) ]phosphine in THF was stirred 24h under argon at 80¡ãC. Then, 3 mL of toluene followed by 30 mL of diethyl ether were added to the mixture at room temperature. The white precipitate was filtered off and washed with 2 x 25 mL of diethyl ether and purified by chromatography with a mixture of acetone / petroleum ether (2 : 7) as eluent. The phosphonium salt (Il’d) was isolated in 63percent yield. Pale yellow solid. 31P NMR (121 MHz, CDCl3) : 5(ppm) = +26 (s)., 18437-78-0
18437-78-0 Tris(4-fluorophenyl)phosphine 140387, achiral-phosphine-ligands compound, is more and more widely used in various fields.
