A pyridinium-based complex with environmentally friendly Zn-II ion was synthesized and used as a green catalyst for the oxidation of alcohols into aldehydes. The metal coordination enhanced electron transfer efficiency, improving photocatalytic performance and facilitating sustainable reaction conversions.
A pyridinium-based complex with environment-friendly and earth-abundant Zn-II ion was synthesized and explored as a green catalyst applied in activating molecular oxygen for the simple and efficient photooxidation of alcohols into aldehydes under additive-free and mild conditions. The metal coordination was conducive to promoting the electron transfer efficiency and introducing the heavy-atom effect for the increased generation of O-center dot(2)- and O-1(2). Accordingly, improved photocatalytic performance of this complex compared to its precursor, no matter activity or selectivity, was obtained, facilitating the transformation of alcohols into aldehydes in a sustainable way.
