<p>Allylic styrene ether compounds of the formula: <CHEM> where R<1> is an optionally substituted allylic or propargyl hydrocarbon group, and R<2>, R<3>, and R<4> are independently H, C1-6 hydrocarbon or C1-6 hydrocarbonoxy groups, are prepared in a single pot reaction from relatively low cost materials. The method includes the steps of reacting a 4-acyloxystyrene of the formula <CHEM> where R is an acyl group, with at least one mole of a base which can readily saponify or hydrolyze the phenolic ester bond per mole of acyloxystyrene, and then adding to the reaction mixture an alkylating agent of the formula R<1>X, where R<1> is as previously defined and X is chloride, bromide, iodide, a sulfonic ester or a hydrocarbon sulfate group, to form said allylic styrene ether compound. The method may be employed to prepare mono-styryl functional compounds or distyryl functional compounds such as 1,4-bis(4'-vinylphenoxy)but-2-ene.</p> |
