Six cation-templated halometal complexes and C–H activation of alkylene-bridged azoles
摘要:
Six dication-templated complexes were discovered in efforts to investigate the effect of linear imidazolium-based template, 1,omega-bis(3,3 '-methylimidazolium)alkyl dibromide, on pure inorganic halometal clusters. Complexes {[C-4(Mim)(2)](Pb2I6)}(n) (1) (omega = 4), {[C-1(Mim)(2)] (Ag2I4)}(n) (2) (omega = 1), {[C-3(Mim)(2)](Ag2I4)}(n) (3) (omega = 3), and {[C-4(Mim)(2)](Ag2I4)}(n) (4) (omega = 4) possess 1-D chain architecture with different organic cations trapped in it. Compound {[C-3 '(Mim)(2)](CuBr3)} (5) (omega = 3) contains the mononuclear anion (CuBr3)(2-) and intra-molecular coupled organic cation with the formed seven-membered ring. {[C-2(Mim)(2)S-2](2)(Cu2I2)}(n) (6) (omega = 2) presents an infinite 2-D coordination polymer as the first representative polyrotaxane example featuring the biimidazolium thiolate cation ligand. All compounds were further characterized with IR spectra and thermal analysis properties.

Molybdenum Chalcogenides for Photo-Oxidative Desulfurization of Liquid Fuels Under Ambient Conditions: Process Optimization, Kinetics, and Recyclability Studies
oxidative desulfurization studies carried out on hydrocarbon-based liquid fuels, with molybdenum chalcogenides as catalyst. Our aim was to understand the synergistic effect of different chalcogenide elements present within the same molybdate compound towards the desulfurization process. Thus, in the present study, the desulfurization activity of hetero-chalcogenide molybdate anions, viz. the dioxo-dithio-molybdate
