Cu(NO3)2·3H2O in THF proceeds smoothly at room temperature under ambient atmosphere to produce the corresponding biaryls in good to high yields. Diaryldimethyltins can be prepared in high yields by the reaction of aryllithiums with dichlorodimethyltin.
Bithiophene-fusedbenzo[c]phospholes were successfully prepared by a TiII-mediated cyclization of dialkynylated bithiophene derivatives. It was revealed that the optical and electrochemical properties of the bithiophene-fusedbenzo[c]phospholes are deeply related to the π-conjugation modes at the fused bithiophene subunits. Both experimental and theoretical results demonstrate that the appropriately
Arsenic‐substituted [5]radialene has been developed as a stabile [5]radialene derivative. Its structure, optical and electronic properties, and stability have been experimentally and computationally studied here.
synthesized dithieno[3,4-b:3′,4′-d]phosphole derivatives as a new type of thiophene-fused phospholes. These dithienophospholes were found to show intramolecular charge transfer interactions by introducing electron-donating or -withdrawing groups on the peripheral aryl groups. Namely, they exhibit the unique hybrid character of electron-withdrawing phosphole and electron-donating thiophene.
