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 alkylgroupmigration has to occur before the metaphosphate species can be extruded from the system.

Silicagel was employed to react with the suspected metaphosphate intermediate of the acid-promoted cleavage of monoalkyl α-(oxyimino)benzylphosphonates. The silicagels displayed CP-MAS 31P NMR signals at about δ −8. A similar value was obtained for silicagel phosphorylated with ethylmetaphosphate from a different source (thermolysis of a P-ethoxy 2,3-oxaphosphabicyclo[2.2.2]octene derivative.
