Fluoro Group Pivoting Dual Hydrogen Bonding Intramolecular Bridge for 1,2-Bis(2-fluorophenyl)acenaphthenediol Molecule in Solution: NMR Spectrometrical Confirmation of Simultaneous Participation of F–C(sp²) Group to Through-space-couplings with Aromatic and Hydroxy Hydrogen Atoms

Crystal structure of 1,2-bis(4-fluorophenyl)-1-hydroxy-2,3,8-trimethoxyacenaphthene: formation of a five-membered intramolecular O—H...O hydrogen-bonded ring

“…Bearing this in mind, the authors have continued their crystallographic study of homologous and analogous peri-aroylnaphthalene compounds for elucidation of the correlation between molecular structure, crystal packing and non-covalent bonding interactions. As one of the readily performable reactions of peri-aroylnaphthalene compounds, a Zn-mediated reductive coupling to 1,2-diaryl-1,2-acenaphthenediol has been discovered (Mido et al, 2017(Mido et al, , 2020. Herein, the crystal structure of 1,2-bis(4-fluorophenyl)-1-hydroxy-2,3,8-trimethoxyacenaphthene (I), a monoalkoxylated derivative of a pinacol-coupling product, is reported and its structural features are discussed through comparison with homologues.…”

Crystal structure of bis(1,8-dibenzoyl-7-methoxynaphthalen-2-yl)terephthalate: Terephthalate phenylene moiety acts as bidentate hydrogen acceptor of bidirectional C-H···π non-classical hydrogen bonds

“…Based on the observation results of crystal structural analysis, the method for evaluating the actual stabilizing interactions of aromaticring-bearing molecules in solid states should be developed. The authors have investigated synthesis, reaction behavior, and analysis of spatial organization of single molecular and accumulation states of peri-aroylnaphthalene homologous compounds in which two aroyl groups are substituted at the adjacent inner carbons of the naphthalene ring [31][32][33][34], accompanying with various related compounds [35,36]. In particular, the authors have reported the crystal structures of these compounds as nearly a hundred articles.…”
