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