  In situ prepared Cp2ZrCl⊕ catalyzes the formation of dioxolenium ions from α,β-unsaturated epoxy esters. As a consequence of this activation process, acrylate, methacrylate and crotonate derivatives undergo a rapid and stereoselective cationic [4+2] cycloaddition with a wide range of dienes. Ring-extended carboxylic acid derivatives are formed in 1–7 h at 0–21 °C and in 50–90% yield after saponification

These polymer precursors are obtainable as the product of a reaction between an optionally substituted terminal phosphate or H-phosphonate ester and compound comprising at least one oxiranyl, preferably epoxy, ring adjacent an alkylidenylcarbonyloxy group. The polymer precursors can be copolymerised with other monomers to produce copolymers such as phosphorus containing polyurethanes which for example have use as flame retardants, anti-corrosives, pigment dispersants and/or adhesion promoters.
