Abstract

The green synthesis of chloropropylene carbonate via the coupling reaction of carbon dioxide and epichlorohydrin had been achieved using halogen-free and single-component catalysts tetrabutylammonium salts of tritransition-metal- substituted A-α-tungstogermanate [(n-C₄H₉) ₄N]₃H₇GeW₉M₃(H ₂O)₃O₃₇ (M = Cu^II, Ni^II, Co^II and Mn^II) without any solvent. The catalytic activity was significantly depended on the transition metal introduced in polyoxometalates. [(n-C₄H₉)₄N] ₃H₇GeW₉Mn₃(H₂O) ₃O₃₇ exhibited the highest catalytic activity with 94.9% conversion for epichlorohydrin and 98% selectivity for chloropropylene carbonate in 3 h. Plausible mechanism was proposed based on the results.
