Halide-free CO₂ cycloaddition onto styrene oxide catalysed by first row transition-metal derivatives of polyoxotungstates

Abstract

Quaternary ammonium salts of metal derivatives of polyoxometalates [XW11O39M(H2O)]n- (X = P, Si; M = Cr, Mn, Co, Ni, Zn) were successfully tested instead of quaternary ammonium halides as catalysts...
