Manganese complexes decomposition

The only exception are manganese(III) complexes, since in this case, the active species is apparently a radical formed during the manganese complex decomposition, which occurs independently of the alkane. 

The M 114.02 clusters were more active than the Mn30 clusters and the Mn clusters also catalyzed t-butyl hydroperoxide decomposition ( 1%) to acetone and methanol, which prevented reliable analysis of methane activation results. We could not compare the dinuclear manganese complexes to their tri and tetra analogues because of relative solubility differences however, we were able to do this with several iron di and tetra clusters and found that the Fe402 clusters were more active with the hydrocarbons studied. Therefore, higher nuclearity or a variety of ligands may provide the shape selectivity we seek fa ultimate methane activation with Mn and Fe clusters. 

Key words Biomimetic, H2O2 decomposition. Polynuclear manganese complex.

Manganese(IV) oxide is a dark-brown solid, insoluble in water and dilute acids. Its catalytic decomposition of potassium chlor-ate(V) and hydrogen peroxide has already been mentioned. It dissolves slowly in alkalis to form manganates(lW), but the constitution of these is uncertain. It dissolves in ice-cold concentrated hydrochloric acid forming the complex octahedral hexachloromangan-ate(IV) ion ...
