The effect of the electron-withdrawing fluorine, chlorine, and bromine atoms on electronic optical properties crystalline tetrathienoanthracene tetrathionoacridine derivatives were investigated by dispersion-corrected density functional theory. Our results also show that position sulfur substitution CH group with a nitrogen atom can improve charge transport title compounds. In addition, slight ...

5-pyrrolidino-m-terphenyl (1) is synthesized via a Buchwald-Hartwig cross-coupling reaction. This terphenyl readily halogenated under ambient conditions with tetrabutylammonium tribromide to generate 4-pyrrolidino-2,6-diphenylbromobenzene (2). The reaction of (2) magnesium results in the conversion its corresponding Grignard reagent (3). Quenching (3) water recovery (1), demonstrating ability r...

A series of oxoperoxovanadium(V) complexes (ligands: H3nta ) nitrilotriacetic acid, H3heida ) N-(2hydroxyethyl)iminodiacetic acid, H2ada ) N-(2-amidomethyl)iminodiacetic acid, Hbpg ) N,N-bis(2-pyridylmethyl)glycine, and tpa ) N,N,N-tris(2-pyridylmethyl)amine) were characterized as functional models for the vanadium haloperoxidase enzymes. The crystal structures of K[VO(O2)Hheida], K[VO(O2)ada],...
