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.
