Thermolysis of dialkyl 2-acyloxyalkylphosphonates, resulting in the fragmentation to an alkene, ester and alkyl metaphosphate, represents the first example of a reaction in which alkyl group migration has to occur before the metaphosphate species can be extruded from the system.

Silica gel was employed to react with the suspected metaphosphate intermediate of the acid-promoted cleavage of monoalkyl α-(oxyimino)benzylphosphonates. The silica gels displayed CP-MAS 31P NMR signals at about δ-8. A similar value was obtained for silica gel phosphorylated with ethyl metaphosphate from a different source (thermolysis of a P-ethoxy 2,3-oxaphosphabicyclo[2.2.2]octene derivative.
GENERATION OF ESTER AND AMIDE DERIVATIVES OF METHAPHOSPHORIC ACID BY PHOTOLYSIS OF 2,3-OXAPHOSPHABICYCLOOCT-5-ENE DERIVATIVES

Irradiation at 254 nm of P-NMe2 and P-OEt derivatives of phosphonates where P is incorporated into the 2,3-oxabicyclooct-ene framework results in fragmentation of the molecules to release N,N-dimethylamino metaphosphoramidate and ethyl metaphophate, respectively.Both species polymerize rapidly, but are effectively trapped as phosphate derivatives when alcohols are included in the reaction mixtures.
