ABSTRACT:
A hybrid homogeneous-heterogeneous catalyst containing catalytic groups, wherein the catalytic activity of the catalyst is largely provided as a result of the interaction of catalytic groups in a suitable proximity and disposition to other catalytic groups, the proximity and disposition resulting from statistical considerations, wherein an example of such catalyst is a polypyrrole-ferrocene monosulfate represented by Formula IV.
