Microwave induced synthesis of O,O-dialkyl dialkylpyrophosphonates under solvent free conditions: Markers of nerve agents

This article describes a one pot, solvent free, microwave assisted synthesis of O,O-dialkyl dialkylpyrophosphonates (DADAPP) from O-alkyl alkylphosphonic chlorides 2a?j with 4-dimethylaminopyridine (DMAP) in the presence of water under microwave irradiation. The reaction takes place by the phosphonium salts, which are converted into the DADAPPs 4a?j. These DADAPPs are important markers of chemical warfare agents sarin, soman, and VX and their analogues. The method has several advantages over the conventional methods such as operational simplicity, high yield, and reduced reaction time. CSIRO 2008.

Phosphorylation of N-trimethylsilyllactams

Treatment of N-trimethylsilyllactams with phosphoryl chlorides results in mixtures of products, whose formation can be explained by competition between N- and O-phosphorylation. - Key words: N-trimethylsilyllactams, dual reactivity; N-phosphoryllactams, synthesis.
