Abstract

In a quest to find new routes for the functionalization of very strong C─H bonds, such as those found in benzene, we have reported nanoscopic soft-oxometalates-based photocatalytic oxidation of benzene to phenol by dioxygen (O₂) in acetonitrile-water (1:1) solvent under visible light irradiation at room temperature using Eosin Y (EY) as a photosensitizer and (NH₄)₆V₁₀O₂₈.6H₂O as the pre-catalyst. Studies reveal that photosensitizer Eosin Y (EY) transfers an electron to the catalyst V^V ₁₀O₂₈ ^6- under visible light irradiation for in- situ generation of H₂O₂ from O_2, which is followed by efficient hydroxylation of benzene to phenol with a high turnover number of 156.8. The present study is a blueprint for efficient C─H activation via a synergistic combination of photocatalysis and vanadium catalysis, giving excellent yield and selectivity.

纳米级[(NH4)6V10O28.6H2O]n其中n = 27882-90189软金属氧酸盐基光催化剂在环境条件下苯转化为苯酚

为了寻找像苯中那样的强C─H键功能化的新途径，我们报道了在室温可见光照射下，在乙腈-水（1:1）溶剂中，以伊红Y （EY）为光敏剂，（NH4）6V10O28.6H2O为预催化剂，以纳米软金属氧酸盐为基础的双氧（O2）光催化苯氧化为苯酚。研究表明，光敏剂Eosin Y （EY）在可见光照射下将一个电子转移到催化剂VV 10o286 -上，由O2原位生成H2O2，随后苯羟基化反应生成苯酚，转化率高达156.8。本研究是通过光催化和钒催化的协同组合高效活化C─H的蓝图，具有优异的收率和选择性。

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
