Flow pyrolysis of some 2-aryloxy-1,3,2-dioxaphospholanes with ortho-CF3 or F substituents, either alone or in the presence of methanol, has provided evidence for the formation of methaphosphates as intermediates; these highly reactive species then undergo further reaction, depending on the nature of the substituent.Mass spectrometric studies of the starting materials have also suggested the elimination of ethylene and the formation of methaphosphates to a limited extent.
