Synthesis of 4-Difluoromethylquinolines by NHC-Catalyzed Umpolung of Imines

The N-heterocyclic carbene (NHC)-catalyzed umpolung of aldimines for the synthesis of 4-difluoromethylquinoline derivatives is reported. In the presence of NHCs, the intramolecular cyclization of aldimines bearing a moderately electron-poor double…

β-Diketone derivatives: influence of the chelating group on the photophysical and mechanofluorochromic properties

A diphenyl-boron β-diketonate complex was synthesized. Its photophysical properties were studied in solution and in the solid-state, and compared to those of its parent diketone and the corresponding difluoro-boron complex. TD-DFT calculations show…
