2,3-DIHYDROXYQUINOXALINE Usage And Synthesis
Chemical Propertiesoff-white powder
General Description2,3-Dihydroxyquinoxaline(dhq) undergoes electrophilic substitution reaction with sulphuric acid solution and potassium nitrate to form 2,3-dihydroxy-6-nitroquinoxaline. It reacts with Ru3(CO)12 in DMSO to give the Ru(CO)2(dhq)(DMSO) complex.
