摘要

Aryl H-phosphonates react with N-oxides to form previously unknown stable zwitterionic oxyonium phosphates comprising an O--P-O-N(+)Z atomsystem. Their structures were confirmed i.e. by X-ray crystal structure analysis, and some mechanisms were proposed for their formation. Stability during storage and reactivity toward nucleophiles points to their possible synthetic applications.
