*  Immobilized catalysts for alkene oxidation
Tertiary butyl substituted and unsubstituted Schiff base systems containing N,O donor ligands (Salicylaldimines) with aminotriethoxysilane tail were synthesized and complexed to Copper and Cobalt acetate. The ligands were characterized by FTIR and 1 HNMR Spectroscopy. The complexes were characterized by elemental analysis, ESI-Mass spectrometry and IR spectroscopy Mesoporous silica supports (SBA-15 and MCM-41) were synthesized and characterized by Xray diffraction, BET surface analysis and SEM. The tertiary butyl substituted and unsubstituted copper and cobalt salicylaldimine complexes were immobilized on amorphous (Davisil silica gel) and mesoporous supports (SBA-15 and MCM-41). Immobilized catalysts were characterized with Atomic Absorption Spectroscopy, X-ray diffraction, BET surface analysis, IR spectroscopy and SEM. Immobilized catalysts were tested for cyclohexene oxidation using molecular oxygen as cooxidant and hydrogen peroxide as oxidant. In this study the effect of metal, reaction ...
