Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4411-80-7, molcular formula is C12H12N2, introducing its new discovery. Recommanded Product: 4411-80-7
Several dimeric 1,2-bis(2,2′-bipyridinyl)ethane (1,2,6,7,and 9) and 1,2-bis(1,10-phenanthrolinyl)ethane (3,4, and 5) ligands have been synthesized in high yield by oxidative coupling of the corresponding monomeric methylene carbanions using as oxidating agents Br2, I2, and 1,2-dibromoethane.The structure of the compounds obtained from three tetramethyl-2,2′-bipyridines and one tetramethyl-1,10-phenanthroline have been assigned on the basis of their (1)H-NMR spectra.The electronic absorption and emisson properties of these new ligands are reported.They display intense fluorescence spectra.
