Extracurricular laboratory:new discovery of 108-47-4

108-47-4, Name is 2,4-Dimethylpyridine, belongs to chiral-nitrogen-ligands compound, is a common compound. 108-47-4In an article, authors is Arcos, Teresa, once mentioned the new application about 108-47-4.

Electron Spin Resonance Study of the Cobalt(II) Species formed after Room-temperature Photolysis of Aqua(sec-butyl)bis(dimethylglyoximato)cobalt(III) in the Presence of N-Donor Bases

The cobalt(II) species resulting from room-temperature photolysis of aqua(sec-butyl)bis(dimethylglyoximato)cobalt(III) solutions in the presence of various amounts of each of 27 different N-donor bases L were studied by electron spin resonance spectroscopy and the ESR spectra compared, when possible, with those of irradiated solutions of the corresponding compounds.From the ESR results, the bases could be grouped according to the position of the substituents.Both base strength and steric effects seem to play a role in the formation of 1:1 and 1:2 cobalt(II) adducts although no definite correlation between the ESR parameters determined for the various species and basicity was found.
