- Copper(ii)-hydroxide facilitated C-C bond formation: The carboxamido pyridine system: Versus the methylimino pyridine system
-
A copper(ii)-hydroxide-induced carbon-carbon bond formation reaction is explored with the synthesis of an asymmetric carboxamido-methylimino pyridine Cu(i) complex of [CuI(py(N-CO)(NC-C)ph2Me2)2]- (12). Two imine-methyl groups are coupled to form a bridge

- NEAR-INFRARED-RAY-ABSORBING COMPOSITION, NEAR-INFRARED-RAY CUT FILTER USING SAME, MANUFACTURING METHOD THEREFOR, CAMERA MODULE, AND MANUFACTURING METHOD THEREFOR
-
Provided are a near-infrared-ray-absorbing composition having strong near-infrared shielding properties when a cured film is produced, a near-infrared-ray cut filter, a manufacturing method therefor, a camera module, and a manufacturing method therefor. The near-infrared-ray-absorbing composition includes a copper complex obtained by reacting a compound (A) having at least two coordination sites with a copper component.

- Linkage isomerism in transition-metal complexes of mixed (arylcarboxamido)(arylimino)pyridine ligands
-
The synthesis of a series of asymmetric mixed 2,6-disubstituted (arylcarboxamido)(arylimino)pyridine ligands and their coordination chemistry toward a series of divalent first-row transition metals (Cu, Co, and Zn) have been explored. Complexes featuring both anionic N,N,N″-carboxamido and neutral O,N,N-carboxamide coordination have been prepared and characterized by X-ray crystallography, cyclic voltammetry, and UV-visible and EPR spectroscopy. Specifically, RLM(X) (M = Cu; X = Cl-, OAc-) and RL(H)MX2 (M = Cu, Co, Zn; X = Cl-, SbF 6-) complexes that feature N,N,N″- or O,N,N-coordination are presented. Base-induced linkage isomerization from O,N,N-carboxamide to N,N,N″-carboxamido coordination is also confirmed by multiple forms of spectroscopy.

- Microwave-promoted syntheses of pyridine carboxamides and tert-carboximides from novel 6-acetylpyridine-2-carboxylic acid
-
A novel 6-acetylpyridine-2-carboxylic acid (4) was obtained occasionally during the synthesis of asymmetric ethyl 6-acetylpyridine-2-carboxylate (3) from 2,6-dipiclinic acid (1). Compounds 3 and 4 could transform mutually under some specific conditions. T

- Further Pyridine Derivatives Isolated from the Culture Medium of Pseudomonas putida - Genuine Metabolites or Artefacts?
-
From the culture medium of Pseudomonas putida after treatment with CH2N2 besides the expected Pyridine-2,6-di(monothiocarboxylic acid)-di-S-methyl ester a series of pyridine derivatives could be isolated which could be shown to be artefacts formed from pyridine-2,6-di(monothiocarboxylic acid). - Keywords: Pyridine Derivatives, Bacterical Metabolites, Pseudomonas putida, Thiocarboxylic Acid Chemistry
