Diphenylphosphinic acid phenyl ester synthesis
- Product Name:Diphenylphosphinic acid phenyl ester
- CAS Number:1706-96-3
- Molecular formula:C18H15O2P
- Molecular Weight:294.28
Yield:1706-96-3 99%
Reaction Conditions:
with N,N-dimethyl-aniline;1,1'-carbonyldiimidazole in acetonitrile at 20; for 12 h;Inert atmosphere;Reagent/catalyst;Solvent;
Steps:
3 Example 3
109 mg (0.5 mmol) of diphenylphosphoric acid, 47 mg (0.5 mmol) of phenol,N, N-dimethylaniline and 81 mg (0.5 mmol) of carbonyldiimidazole with different molar ratios (0 mol%, 50 mol%, 100 mol%, 150 mol%, 200 mol%) were added under a nitrogen atmosphere mL acetonitrile,The reaction was stirred at room temperature for 12 hours. By GC detection and analysis, the yield of this coupling reaction can reach 99% only when the amount of N, N-dimethylaniline is 1.5 times the reaction equivalent of diphenylphosphoric acid.
