Heterogeneous Selective Oxidation of Alkenes to α,β‐ Unsaturated Ketones over Coordination Polymer MIL‐101

Abstract The mesoporous metal‐organic framework MIL‐101 is an efficient heterogeneous catalyst for the selective allylic oxidation of alkenes with tert ‐butyl hydroperoxide. The selectivity towards α,β‐unsaturated ketones reaches 86–93%. The temperature of the catalyst activation strongly affects the ketone yield. MIL‐101 is stable to chromium leaching, behaves as a true heterogeneous catalyst, can be easily recovered by filtration, and can be reused several times without loss of the catalytic performance.
