Organic–inorganic hybrid catalysts containing new Schiff base for environment friendly cyclohexane oxidation

Organic and inorganic entities have been hybridized using 3-aminopropyltriethoxysilane (APTES) linker for the synthesis of three novel organic–inorganic hybrid catalysts [Cu(<sc>ii</sc>), Co(<sc>ii</sc>) and Ni(<sc>ii</sc>)].
