Cai, Liangzhen published the artcileSynthesis of diarylaminofluorenes through tandem copper and palladium catalyzed coupling-cyclizing reactions, SDS of cas: 145349-62-8, the publication is Youji Huaxue (2015), 35(8), 1682-1690, database is CAplus.
A convenient method of tandem copper and palladium catalyzed coupling-cyclizing reactions was developed for the preparation of diarylaminofluorenes, I, II(R1 = H, Me, R2 = H, Me) . Methylbromotriphenylamines prepared by the copper-catalyzed reaction of substituted iodobenzenes and methylbromoanilines, coupled with chlorophenylboronic acid under palladium catalyst to obtain the chlorophenylmethyltriphenylamines (V). A series of diarylaminofluorenes could be generated in good yields through palladium-catalyzed activation of benzylic C(sp3)-H bond of compound V. It was found that the 2-diarylaminofluorenes or 3-diarylaminofluorenes could be efficiently gotten. These compounds were characterized by1H NMR, 13C NMR, HRMS, IR and UV-vis.
