Methods for the dealkylation of phosphonate esters

摘要

Disclosed are methods for the dealkylation of phosphonate esters by use of trimethylchlorosilane as the dealkylating agent. In particular, this invention is directed to the discovery that high yields for the dealkylation of phosphonate esters can be achieved within relatively short reaction times by the use of trimethylchlorosilane provided that the dealkylation procedure occurs in a sealed vessel containing a compatible solvent.
