The anionic phospho-Fries rearrangement of phosphoric acid (3, 5-di-isopropoxy) phenyl ester diethyl ester () gave rise to (2-hydroxy-4, 6-di-isopropoxy-phenyl) phosphonic acid diethyl ester () in excellent yield. The phenol functionality of was converted to the corresponding triflate which was coupled with vinyltributylstannane, under Stille conditions, to give a styrene. This molecule is intended to serve as the aromatic fragment in the ...
