Cho, Chan Sik published the artcileA recyclable copper catalysis in quinoxaline synthesis from α-hydroxyketones and o-phenylenediamines, Safety of 2-(Thiophen-2-yl)quinoxaline, the main research area is hydroxyketone phenylenediamine recyclable copper oxidative cyclization quinoxaline preparation; oxidative cyclization catalyst recyclable copper.
O-Phenylenediamines react with α-hydroxyketones in toluene at 100° in the presence of a catalytic amount of a copper catalyst along with MS 4 Å under O2 atmosphere to afford the corresponding quinoxalines in high yields. The catalytic system could be easily recovered and reused several times without any loss of catalytic activity.
Journal of Organometallic Chemistry published new progress about Aromatic diamines Role: RCT (Reactant), RACT (Reactant or Reagent). 40353-41-1 belongs to class quinoxaline, name is 2-(Thiophen-2-yl)quinoxaline, and the molecular formula is C12H8N2S, Safety of 2-(Thiophen-2-yl)quinoxaline.
