Facile synthesis of 1,7,8-trifluoro-2-naphthol via DMAP catalyzed cycloaromatization

A facile synthesis of 1,7,8-trifluoro-2-naphthol, an important synthetic intermediate for liquid crystal compounds with a 1,7,8-trifluoronaphthalene structure, was developed starting from 4-bromo-1,2-difluorobenzene via DMAP catalyzed intramolecular cycloaromatization in 51% overall yield for the 6 steps.

Unilaterally Fluorinated Acenes: Synthesis and Solid-State Properties

The rapid development of organic electronics is closely related to the availability of molecular materials with specific electronic properties. Here, we introduce a novel synthetic route enabling a unilateral functionalization of acenes along their long side, which is demonstrated by the synthesis of 1,2,10,11,12,14-hexafluoropentacene (1) and the related 1,2,9,10,11-pentafluorotetracene (2). Quantum chemical DFT calculations in combination with optical and X-ray absorption spectroscopy data indicate that the single-molecule properties of 1 are a connecting link between the organic semiconductor model systems pentacene (PEN) and perfluoropentacene (PFP). In contrast, the crystal structure analysis reveals a different packing motif than for the parent molecules. This can be related to distinct F???H interactions identified in the corresponding Hirshfeld surface analysis and also affects solid-state properties such as the exciton binding energy and the sublimation enthalpy.
