Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 28903-71-1, is researched, SMILESS is COC1=CC=C(C=C1)C(C2=[N]3[Co+2]4([N-]56)[N-]7C(C(C8=CC=C(C=C8)OC)=C3C=C2)=CC=C7C(C9=CC=C(C=C9)OC)=C%10C=CC%11=[N]4%10)=C5C=CC6=C%11C%12=CC=C(C=C%12)OC, Molecular C48H38CoN4O4Journal, Science China: Chemistry called Photocatalyst-controlled and visible light-enabled selective oxidation of pyridinium salts, Author is Peng, Xiang-Jun; He, Hai-Ping; Liu, Qian; She, Kun; Zhang, Bao-Qi; Wang, Heng-Shan; Tang, Hai-Tao; Pan, Ying-Ming, the main research direction is alkylpyridinium halide rhodamine photocatalyst regioselective ring opening recyclization green; alkylpyrrole carbaldehyde preparation; arylmethyl pyridinium halide cobalt catalyst regioselective photooxidation rearrangement green; aryl pyridinyl methanone preparation.Name: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II).
This study proposed two different methods of photocatalytic-controlled and visible light-induced selective oxidation of pyridiniums with air as the terminal oxidant. The key to these transformations was to choose the appropriate light source and photocatalyst. Pyridiniums were successfully converted into pyrroles through oxygen-mediated cycloaddition, proton-coupled electron transfer (PCET), pyridine ring opening, and recyclization. The other route was that pyridiniums selectively form 4-carbonyl pyridines through free radical rearrangement/aerobic oxidation under the catalysis of cobalt (II).
After consulting a lot of data, we found that this compound(28903-71-1)Name: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II) can be used in many types of reactions. And in most cases, this compound has more advantages.
