Mechanistic Insights into the Conversion of Cyclohexene to Adipic Acid by H2O2 in the Presence of a TAPO-5 Catalyst

The stereochemistry of the 1,2‐cyclohexanediol intermediate plays an important role with regard to both the rate and selectivity of the production of adipic acid from cyclohexene in the absence of an organic solvent. A titanium‐containing aluminophosphate molecular sieve (TAPO‐5) is shown to serve as a good heterogeneous catalyst for this reaction.
