Dipolar Character of Ligand-Centered Transitions in Transition Metal Tris-bipyridine Complexes
Stark spectra Tris-bipyridyl complexes UV spectroscopy Zn complexes
2016/5/23
The Stark spectra of bipyridine (bpy) and the metaltris(2,2'-bipyridine) complexes of Zn, Fe, Ru and Os have been measured in the ligand-centered region in the near UV. The results show that excitatio...

Investigation of the Cation Complexation by Macrocyclic Ethers using 13C NMR Spin--Lattice Dipolar Relaxation Time Measurements
Investigation the Cation Complexation Macrocyclic Ethers using 13C NMR Spin--Lattice Dipolar Relaxation
2010/4/19
The binding constants (Ka) of [18]crown-6 ether with Na+ , K+, and Ba2+ thiocyanates were determined by 13C{1H} NMR spin--lattice dipolar relaxation time measurements. The observed relaxation times (T...
Synthesis of Some New Isoxazolidines by 1,3-Dipolar Cycloaddition Reaction of Nitrones and Olefins
Isoxazolidine Nitrones 1,3-Dipolar Cycloaddition
2010/4/20
A series of new isoxazolidines 5a-j were synthesized by 1,3-dipolar cycloaddition reaction of different nitrones with substituted olefins under reflux condition. The yields of products following recry...
