Abstract

Monomeric methyl metaphosphate (CH₃OPO₂), a highly electrophilic phosphorylating intermediate in chemical oligonucleotide synthesis, has been generated in the gas phase by high-vacuum flash pyrolysis (1000 K) of methyl 2-butenylphosphonate. In addition to the unambiguous characterization using IR spectroscopy in solid N₂-, Ar-, and Ne-matrices, the formation CH₃OPO₂ in the photooxidation of the prototypical phosphinidene oxide CH₃PO by O₂ with ¹⁸O-isotope scrambling has been observed in the solid N₂-matrix (15 K).
