Synthesis, characterization, and coordination chemistry of the 2-azaphenalenyl radical
The 2-azaphenalenyl radical 2 has been synthesized and characterized by ESR spectroscopy. Variable-temperature ESR measurements were carried out on both the phenalenyl (1) and the 2-azaphenalenyl (2) radicals. The phenalenyl radical 1 has the known propen
COMPOUND FOR ORGANIC ELECTRONIC ELEMENT, ORGANIC ELECTRONIC ELEMENT COMPRISING THE SAME, AND ELECTRONIC DEVICE THEREOF
Disclosed are: a compound represented by chemical formula 1; an organic electronic element including a first electrode, a second electrode, and an organic material layer between the first and second electrodes; and an electronic device including the organic electronic element. By including the compound represented by the chemical formula 1 in the organic material layer, the organic electronic element can have decreased driving voltage, and improved luminous efficiency and lifetime.COPYRIGHT KIPO 2018

Asymmetric synthesis catalyzed by chiral ferrocenylphosphine transition metal complexes. 10 gold(I)-catalyzed asymmetric aldol reaction of isocyanoacetate
Optically active ferrocenylbisphosphine ligands containing 2-(dialkylamino)ethylamino group on the ferrocenylmethyl position have been prepared and used for the gold(I)-catalyzed asymmetric aldol reaction of isocyanoacetate with aldehydes. Six-membered ring amines, such as morpholino or piperidino group, at the terminal of the side chain were most stereoselective to give optically active trans-4- methoxycarbonyl-5-alkyl-2-oxazolines (up to 97% ee) with high enantio- and diastereoselectivity in a quantitative yield.
