Jacobson, Mares, and Zambri report that the lithiation of 1% crosslinked polystyrene followed by treatment with triethoxyarsine and with hydrogen peroxide affords (Equation 5) the polymer-bound arsonic acid (30). 

Epoxidation catalysis by arsonic acids (both free and polymer-bound) had been reported as early as 1979 by Jacobson et al. [29]. However, these early experiments were typically carried out in 1,4-dioxane as solvent. The latter had been identified as an optimal solvent, as it is miscible both with the aqueous oxidant and the organic...
