One-pot oxidative cleavage of cyclic olefins for the green synthesis of dicarboxylic acids in Pickering emulsions in the presence of acid phosphate additives

Abstract

Dicarboxylic acids were prepared by the one-pot oxidative cleavage of cyclic alkenes with aqueous H₂O₂ by adsorbing dodecyltrimethylammonium phosphotungstate nanoparticles, and silica particles functionalized with octadecyl chains and sulfonic acid groups, C₁₈/C₃SO₃H, at the W/O interface. Na₂HPO₄ and [C₁₂]H₂PO₄ conditioned the interlocking and self-assembly of the particles, enhancing the catalytic selectivity, especially for cyclooctene.
