标 题 :One step synthesis for quinacridone compounds
发明人：COSIMBESCU LELIA
权利人:EASTMAN KODAK CO
摘要:Disclosed is a process for forming a N,N'-diarylquinacridone compound comprising the step of reacting a N,N'-unsubstituted quinacridone compound with a haloaryl compound in the presence of a metal or metal compound to arylate the N and N' positions and form the corresponding N,N'-diarylquinacridone compound. The process is versatile and provides high yields and purity for the synthesis of N,N'-diarylquinacridone compounds.
