Triphenylphosphine → HCID 117966963, compound

Participants

Reaction Steps

In 30 ml of tetrahydrofuran were dissolved 0.3 g (1.19 mmol) of 2,4-dimethyl-5-(2,2,2-trifluoroethylsulfinyl)phenol, 0.29 g (1.41 mmol) of 2-(4′-trifluoromethoxyphenyl)ethanol and 0.41 g (1.56 mmol) of triphenylphosphine. Thereto was added 0.31 g (1.53 mmol) of diisopropyl azodicarboxylate at room temperature, and stirred for 16 hours. The solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (developing solvent: a mixed solvent of n-hexane:ethyl acetate=5:1), and the residue was washed with n-hexane, to obtain 0.21 g (yield: 40%) of an intended product.
