Abstract
Trichloroisocyanuric acid–KF afforded dialkylfluorophosphates from dialkylphosphites at room temperature through a facile electrophilic–nucleophilic metathesis.
ACKNOWLEDGMENT
We thank Dr. R. Vijayaraghavan, director, DRDE, Gwalior, for his keen interest and encouragement.
Notes
a isolated yield.
b 31P NMR spectra were recorded at 162 MHz in CDCl3. All the products gave satisfactory IR, NMR, and GC-MS data compared with authentic samples.
Note. Caution! Dialkylfluorophosphates are highly toxic compounds and should be synthesized by trained persons using an efficient fume hood. Great caution should be exercised especially while distilling them, and residue must be properly decontaminated by using 20% alkali solution.
