Li, Yong-Hui published the artcileOsmium(II) complexes for light-driven aerobic oxidation of amines to imines, COA of Formula: C8H5F3N4, the publication is Dalton Transactions (2016), 45(31), 12400-12408, database is CAplus and MEDLINE.
The synthesis and characterization of three Os(II) complexes [Os(fptz)2(L1)] (fptzH = 3-trifluoromethyl-5-pyridyl-1,2,4-triazole), I (L1 = PPhMe2, PPh3, pyridine; L2 = PPhMe2, CO) that were successfully utilized as good photocatalysts to promote aerobic oxidative coupling of amines to imines with mol. oxygen in air as a green oxidant was described. Complex I (L1 = L2 = PPhMe2) was the most effective catalyst for the oxidative coupling of benzylamine with mol. O2 (air) as the oxidant because of the complex’s strong absorption of visible light and long-lived triplet state. The application of a low catalyst loading (0.06 mol%) of complex I (L1 = L2 = PPhMe2) to the oxidative coupling of a wide range of amines afforded the corresponding imines efficiently and selectively in most cases. The reaction mechanism was investigated via relevant control and quenching experiments The results indicated that the reaction occurs via an active 1O2-involved pathway. The 1O2-generating ability of complex I (L1 = L2 = PPhMe2) as a photosensitizer was evaluated using 9,10-dimethylanthracene (DMA) as a chem. trap for 1O2.
