p-Methyl-N-(pentafluorobenzylidene)aniline (1), 1,2,3,4-tetrafluoro-7-methoxyacridine (2), 1,2,3,4,7-pentafluoroacridine (3) and 3-(p-methylanilino)-1,2,4-trifluoro-7-methylacridine (4): four molecules representing key stages inthe one-pot synthesis of 1,2,3,4-tetrafluoroacridines by treating pentafluorobenzaldehyde with para-substituted anilines

Herringbone structures of 2,7-dihalogenated acridine tailored by halogen–halogen interactions

“…Despite the importance of both acridine and halogen-halogen interactions, there have been only two reports of crystallographic analysis of halogenated acridines without any other substituents; 9-chloroacridine [30] and 3,5,6,7,8-pentafluoroacridine [31]. Halogen-halogen interaction was seen only in 3,5,6,7,8-pentafluoroacridine.…”

Pentafluorobenzaldehyde and its utilizing in organic synthesis

“…This condensation products undergo S N Ar reactions of ortho-and para-fluorine in the presence of excess arylamine (Scheme 76 [611][612][613][614][615][616][617]). The ratio of two forming product (85, 86a-g) changes depended on the substituents and on amount aniline utilized.…”

Self-assembly of gold nanoparticles on functional organic molecular crystals

“…1c), while the second one, 1,2,3,4-tetrafluoro-7-methoxy-acridine (MeOAcr) (Fig. 1b), exposes the same density of oxygen atoms at the (0 1 0) face [16] (Fig. 1d).…”
