Abstract:
1. A process for preparing a substituted or unsubstituted 9,10-diaryl anthracene comprising: reacting a substituted or unsubstituted anthracene with a halogenating agent to yield a halogenated anthracene, wherein the halogenating agent comprises an oxidizing agent; reacting the halogenated anthracene with a palladium complex to yield a palladium intermediate, wherein the palladium intermediate undergoes transmetallation with a boronic ester to yield the substituted or unsubstituted 9,10-diaryl anthracene, concentrating the substituted or unsubstituted 9,10-diaryl anthracene under reduced pressure, and purifying the substituted or unsubstituted 9,10-diaryl anthracene by flash chromatography first with hexane then with dichloromethane, and by sublimation at 320° C.
