Microscale Preparation of Benzyl Quinoxaline Quinoxaline derivatives such as 2,3-diphenylquinoxaline are an important class of nitrogen-containing aspirins that are widely used in pharmaceuticals, dyes, electrical and photochemical materials. One method of preparing 2,3disubstituted syntheses is the Suzuki-Miyaura coupling reaction wherein o-phenylenediamines with or with no substituents on other positions of the Figure 1 benzene ring are condensed with 1,2-dicarbonyl compounds as the one shown in figure 1. Benzil is one such compound. In our reaction the R substituents are phenyl, but generally they can vary.
