Abstract:

It is a challenge to oxidize inert hydrocarbons with molecular oxygen, which can be easily realized by enzymes under mild conditions. Inspired by the catalytic mechanism of enzymes, we used the composite material CuPW11@HKUST-1, consisting of encapsulated Keggin-type polyoxometalate [CuPW11O39]5-(abbreviated as CuPW11) in the pore space of metal-organic framework HKUST-1, as a redox catalyst, and N-hydroxyphthalimide(NHPI) as a co-catalyst, for the biomimetic aerobic oxidation of arylalkanes under mild conditions. The biomimetic system exhibits enzyme-like features of high efficiency and high selectivity in the aerobic oxidation of arylalkanes by imitating the structural features, active sites and catalytic mechanism of enzymes, in which up to 99% yield and 17700 turnover number(TON) have been realized in the aerobic oxidation reaction. This work offers a feasible pathway for highly efficient aerobic oxidation of inert organic molecules under mild conditions.
