摘要:
A binuclear complex (MAMBL2+)-M-II-L-IV [with M-A(II)=Co-II and M-B(IV) =V-IV] has been synthesized with a macrocyclic ligand prepared by condensing 2 equiv. of 2,6-difonnyl-4-methylphenol with 2 equiv. of 1,2-phenylenediamine. This has been immobilized on a carbamate-modified alumina support by covalently binding it to the surface. The TGA analysis of the final catalyst showed that it is thermally stable up to 251 degrees C and it has been shown that it serves as a catalyst for oxidation of cyclohexane, forming cyclohexanone and cyclohexanol in the ratio of 14:1 as identified by the GC/MS analysis.
