✦ Synopsis

Some polystyrene-supported porphyrinatoiron( III) with different stereostructure were prepared using a new method and characterized by EA, UV-Vis,IR and EPR. Their catalytic activities in hydroxylation of cyclohexane with molecular oxygen have been found to be high compared with corresponding non-supported porphyrinatoiron(II1).

The difference of the catalytic activities of these polystyrene-supported porphyrinatoiron( III) are discussed through stereostructure of porphyrinatoiron( III) molecule relative to surface of polystyrene.

## Abstract We have prepared silica‐ and magnesia‐supported poly(3‐aminopropylsiloxane)‐platinum complexes (abbreviated as SiO~2~‐PAPSPt and MgO‐PAPSPt, respectively) in which mixed valent platinum is coordinated by amino groups and aggregated to a certain extent. MgO‐PAPSPt contains low‐valent, ve
