New carboxy-functionalized terpyridines as precursors for zwitterionic ruthenium complexes for polymer-based solar cells
摘要:
New carboxy-terpyridines selectively functionalized at the 4-, 4'- and 4"-positions were prepared in a three-step procedure with good yields using, the Krohnke reaction followed by saponification. Their complexation with ruthenium led to symmetric and unsymmetric terpyridinyl zwitterionic complexes. (c) 2006 Elsevier Ltd. All rights reserved.

formation from aldehydes and alkynes, a new reaction pathway involving propargyl amines as intermediates that do not undergo rearrangement is presented. The formation of indolizines or chalcones is driven by inductive and solvent effects, with a wide array of both being reported. In both reactions, the nanoparticulate catalyst has been shown to be superior to some commercially available copper catalysts

Solvent decides: Versatile coppernanoparticles (Cu NPs) on activated carbon have been found to catalyze the multicomponent synthesis of indolizines in dichloromethane and the synthesis of heterocyclicchalcones in the absence of solvent, in both cases, from pyridine‐2‐carbaldehyde derivatives, secondary amines, and terminal alkynes (see scheme).

of [Mn(CO)3(L)Br] complexes (1–5) are synthesized using azachalcones as ligands, wherein they are coordinated to the manganese metal through the nitrogen and oxygen donor atoms. Their characterization using various spectroscopic techniques, stability analysis in dimethyl sulfoxide solvent, photodecomposition analysis, and antiproliferative effect are reported herein. These complexes release CO upon
