Umile, T. P. and Groves, J. T. , Catalytic Generation of Chlorine Dioxide from Chlorite Using a Water-Soluble Manganese Porphyrin. Angewandte Chemie International Edition
The cationic, water soluble manganese imidazolium porphyrin [Mn(TDMImP)] efficiently catalyzes the dismutation of chlorite ion (ClO2−) to chlorine dioxide. The gaseous product ClO2 could be isolated in 60 % yield (500 turnovers at 0.5 turnover s−1) and the catalyst was completely recovered. Oxo-transfer from chlorite to the MnIII catalyst is proposed to be the rate limiting step. An immobilized form of the catalyst was also active.
