Abstract

The cationic, water soluble manganese imidazolium porphyrin [Mn(TDMImP)] efficiently catalyzes the dismutation of chlorite ion (ClO 2 -) to chlorine dioxide. The gaseous product ClO 2 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 Mn III catalyst is proposed to be the rate limiting step. An immobilized form of the catalyst was also active.
