Theoretical and experimental study of donor-bridge-acceptor system: model 2-[5-(9H-fluoren-9-ylidenemethyl)thiophen-2-yl]-1,3,4-oxadiazole derivatives

Abstract: The theoretical study of the titled model acceptor-bridge-donor molecular series based on 9H-fluoren-9-ylidenemethyl and 1,3,4-oxadiazole heterocycles is presented. The subunits are linked through a thienyl moiety, and the second α-site of oxadiazole was modified. The quantum chemical model indicated that the electron-donating properties of 9H-fluoren-9-ylidenemethyl were significantly supported or suppressed by the terminal substitution of 1,3,4-oxadiazole which affected the possible semiconductivity. Finally, the possible synthesis of selected molecules is described, and the prepared derivatives were fully characterized by 1H NMR, 13C NMR, IR, and elemental analysis together with optical and electrochemical measurements.

Synthesis of 9-Fluorenylidenes via Pd-Catalyzed C-H Vinylation with Vinyl Bromides

A facile and efficient approach for the synthesis of 9-fluorenylidenes has been developed via the palladium-catalyzed cross-coupling of 2-iodobiphenyls and vinyl bromides. The reaction involves the C-H activation of 2-iodobiphenyls and dual C-C bond formations. A range of 9-fluorenylidene derivatives, including diphenyldibenzofulvenes, can be synthesized with the reaction.

An N-heterocyclic carbene-catalyzed switchable reaction of 9-(trimethylsilyl)fluorene and aldehydes: Chemoselective synthesis of dibenzofulvenes and fluorenyl alcohols

An N-heterocyclic carbene-catalyzed synthesis of dibenzofulvenes and fluorenyl alcohols was developed. In the presence of 10 mol% NHC (1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) and 4 ? molecular sieves, 9-(trimethylsilyl)fluorene undergoes an olef
