We describe a general strategy for synthesizing conjugated microporous fullerene thin films via a high-throughput, efficient and controllable thiophene-based electropolymerization. By virtue of the ambipolar redox charge/discharge of the films, we showed the microporous fullerene films as outstanding pseudocapacitor materials with high capacity and wide potential windows.

Thiophene-based rings are one of the most widely used building blocks for the synthesis of sulfur-containing molecules. Inspired by the redox diversity of these features in nature, we demonstrate herein a redox-divergent construction of dihydrothiophenes, thiophenes, and bromothiophenes from the respective readily available allylic alcohols, dimethyl sulfoxide (DMSO), and HBr. The redox-divergent selectivity could be manipulated mainly by controlling the dosage of DMSO and HBr. Mechanistic studies suggest that DMSO simultaneously acts as an oxidant and a sulfur donor. The synthetic potentials of the products as platform molecules were also demonstrated by various derivatizations, including the preparation of bioactive and functional molecules.

Fe(OTf)3-1,10-phenanthroline catalyzes oxidative coupling of arylboronic acids with benzene derivatives using t-BuOOt-Bu as an oxidant. The reaction proceeds through homolytic aromatic substitution with aryl radicals generated from arylboronic acids and t-BuO.

experimental part, p. 1 - 6 (2010/08/20)
A convenient protocol for the synthesis of biaryls from arenediazonium salts and potassium aryltrifluoroborates in refluxing methanol catalyzed by Pd/C is described. The protocol is simple to execute and gives moderate to high yields of cross-coupling products in most cases.

Toyota, Kozo,Tsuji, Yasutomo,Okada, Kazuyuki,Morita, Noboru
experimental part, p. 127 - 138 (2009/05/07)
Unsymmetrically substituted 1,4-bis(2-ethynyl-3-thienyl)benzene derivative was prepared, utilizing 1-bromo-4-(2-iodo-3-thienyl)benzene and 5-alkyl-3-bromo-2-ethynylthiophene derivatives as key intermediates.
