Synthesis of Binuclear Copper (II) Complexes with Expanded Porphyrins
The synthesis and characterization of some new binuclear copper (II) complexes, based on the use of large, pyrole-containing macrocycles, the so called "expanded porphyrins", [Cu2(macrocycle)]+4 is described. Electron Spin Resonance (ESR) studies indicate a weak "half-field line", which is characteristic of the Cu(II)-Cu(II) dimer, is observed at about 1600G. The obser...
متن کاملInteractions between expanded porphyrins and nucleic acids
Two types of interaction of expanded porphyrins and nucleic acids are discussed. The first involves the specific chelation of the anionic phosphate diester backbone of DNA by the monoprotonated form of the water soluble sapphyrin 2. Support for the proposed binding mode derives from a variety of spectroscopic and biochemical studies, including visible absorption spectroscopy, circular dichroism...
متن کاملsingle-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولPlasma-assisted Electrochemical Synthesis of Pristine Graphene Sheets
Graphene is a two-dimensional form of graphite made up of a single layer of carbon atoms in a honeycomb lattice that has attracted tremendous interest for its novel physical properties. A key challenge that has emerged is how to synthesize large amounts of graphene (large area or mass) at low cost. The objective of this project is to explore an entirely new method to exfoliate graphene from com...
متن کاملCopper-catalyzed arylsulfonylation of N-arylsulfonyl-acrylamides with arylsulfonohydrazides: synthesis of sulfonated oxindoles.
A copper-catalyzed arylsulfonylation of N-arylsulfonyl-acrylamides with sulfonylhydrazides through a tandem radical process was developed. This methodology provided an alternative strategy for the synthesis of sulfonated oxindoles by forming C-S, C-N and C-C bonds in a single operation.
