<p>In one embodiment, alkanes are oxidized by contact with oxygen-containing gas in the presence as catalyst of a metalloporphyrin containing cyano groups on the porphyrin ring. The catalysts may contain, in addition to cyano groups, halogen atoms on the porphyrin ring. In another embodiment, new compositions of matter comprising cyano-substituted metal complexes of porphyrins are catalysts for the oxidation of alkanes. The metal is iron, chromium, manganese, ruthenium, copper or cobalt. The porphyrin ring has cyano groups attached thereto in meso and/or beta -pyrrolic positions.</p> |
