Synthesis, Characterization and Crystal Structure of 1,4,5,8-Tetrakis(Perfluoropyridin4-yloxy) Naphthalene

Abstract

1,4,5,8-tetrakis(perfluoropyridin-4-yloxy)naphthalene (tetra-PPN) was synthesized via a one-pot pseudo-five-component reaction of pentafluoropyridine and 5,8-dihydroxy-1,4-tetralindione under basic conditions in DMF. The asymmetric unit contains one half-mol ecule of tetra-PPN and data reveals that half of the molecule being related to the other via inversion symmetry. A detailed analysis of the intermolecular interactions of the compound has been performed using Hirshfeld surfaces. The optimized geometrical parameters and calculated spectroscopic features obtained by quantum chemical calculations using density functional (DFT) methods. In addition, to support the experimental results, the 19F NMR values are obtained using B3LYP method. The obtained results are compared with experimental values show a very good agreement with the experimental data.
