Reaction Conditions:
with trimethylsilyl iodide at 120; for 12 h;Inert atmosphere;
Steps:
11 Preparation of ethyldiphenylphosphine oxide from diphenylphosphine oxide and ethanol
Diphenylphosphine (101.0 mg, 0.50 mmol) was sequentially added to a 10 mL tubular reactor under nitrogen atmosphere.Ethanol (27.6 mg, 0.60 mmol, 1.2 equiv.) andTrimethylsilyl iodide (50.0 mg, 0.25 mmol, 50 mol%),It was then heated to 120 ° C for 12 h without solvent.The product was purified by column chromatography, and the isolated yield was 95%.
