Fragmentation–rearrangement of 2-acyloxyalkylphosphonates—a novel route to alkyl metaphosphate extrusion
Abstract
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.
