摘要: BACKGROUND: Ketones and aldehydes are important organic chemicals as intermediates for the pharmaceutical fine-chemical industries. The existing oxidation reactions to obtain ketones no longer sustainable because of large amount waste generated use stoichiometric reagents: a cleaner catalytic system needs be developed. RESULTS: experimental results show that cobalt (II) tetra-(perfluorohexyl) phthalocyaninate delivered high activity ethyl benzene (35% conversion 86% selectivity acetophenone) at 90 °C under ambient pressure oxygen. catalyst could recycled least four runs. For benzyl alcohol benzaldehyde, 6% was achieved but with 100% 2 × 105 Pa O2. CONCLUSION: Perfluoroalkyl metallophthalocyanines can used fluorous biphasic molecular exhibited highest benzene. using our method may feasible in industrial applications.
