Selective epoxidation of olefins over Co(II)-Schiff base immobilised on KIT-6

- Covalent anchoring of Co(II)-Salen complex onto KIT-6 was synthesised.
- Selective epoxidation of olefins over Co-S-KIT-6 using H2O2 as the oxidant was reported.
- Solvent polarity played a crucial role for the conversion and product selectivity.
- The Co-S-KIT-6 can be easily recovered and recycled for five cycles.
