Abstract

The structure of a polymer-supported version of the Hendrickson "POP" reagent, prepared by the reaction of polymersupported triphenylphosphine oxide 1 with triflic anhydride, is established as an equilibrium mixture of polymer-supported triphenylphosphine ditriflate 3 (d 79.4 ppm) and polymersupported phosphonium anhydride 4 (d 73.3 ppm). The 31P NMR chemical shift reported previously for 3 is shown to be incorrect.The structure of a polymer-supported version of the Hendrickson "POP" reagent, prepared by the reaction of polymersupported triphenylphosphine oxide 1 with triflic anhydride, is established as an equilibrium mixture of polymer-supported triphenylphosphine ditriflate 3 (d 79.4 ppm) and polymersupported phosphonium anhydride 4 (d 73.3 ppm).
