Difluoro[1-(1-naphthyliminomethyl)-2-naphtholato-N,O]boron

Abstract

The title compound, C21H14BF2NO, was synthesized by the reaction of 3-[(E)-(naphthalen-1-ylimino)methyl]naphthalen-2-ol, diisopropylethylamine and boron trifluoride etherate. The mean planes of the two naphthalene systems make a dihedral angle of 71.97 (4)°. The crystal packing is stabilized by π–π stacking interactions and van der Waals forces.

Triferrocenes Built on a C3-Symmetric Ligand Platform: Entry to Redox-Active pseudo-Triphenylenes via Chelation-Driven Stereoselection of Triple Schiff Bases

“…The quantitative (>99%) and exclusive formation of 6 from an essentially equimolar mixture of 5a and 5b strongly supports the mechanism depicted in Scheme . Related {BX 2 } + (X = F, Cl, or Br) complexes of mononucleating as well as dinucleating N -substituted Schiff base ligands have previously been characterized.…”

Synthesis, structure and spectral study of two types of novel fluorescent BF2 complexes with heterocyclic 1,3-enaminoketone ligands

“…However, there are few reports [9][10][11] available on the generation of difluoroboron complexes with N, O double-dentate ligands. Although we have reported [12] the synthesis and X-ray crystallography of a difluoroboron complex containing the N, O double-dentate ligand derived from a Schiff 0 s base of salicyaldehyde, its poor quantum yield and low fluorescence intensity compelled us to explore other approaches to such compounds.…”
