Dissymmetrization of Benzothiadiazole by Direct C–H Arylation: A Way to Symmetrical and Unsymmetrical Elongated π-Conjugated Molecules

5-(7-Bromo-2,1,3-benzothiadiazol-4-yl)-2-thiophenecarbaldehyde is a small building block of great interest for its use in the elaboration of symmetrical or unsymmetrical donor–acceptor π-conjugated molecules for optoelectronic applications. Herein, a convenient, one-pot, two-component synthesis of this intermediate is reported, based upon a palladium-catalysed, phosphine- and additive-free, direct C–H arylation process. The synthesis has been studied in depth to obtain optimum yields and selectivity by an efficient and environmentally friendly strategy for sustainable synthesis.

Synthesis of functionalized 2-arylthiophenes with triarylbismuths as atom-efficient multicoupling organometallic nucleophiles under palladium catalysis

Atom-efficient cross-coupling reactions of functionalized 2-bromo- and 2-iodothiophenes have been demonstrated using triarylbismuths as atom-efficient multicoupling organometallic nucleophiles under palladium-catalyzed conditions. These couplings with various functionalized triarylbismuths proceeded smoothly to afford the corresponding functionalized 2-arylthiophenes in high yields. Georg Thieme Verlag Stuttgart · New York.

Palladium-catalysed direct C-H activation/arylation of heteroaromatics: An environmentally attractive access to bi- or polydentate ligands

Bi- or polydentate ligands based on heterocycles can be easily prepared by palladium-catalysed C-H bond activation of heteroaromatics followed by heteroarylation with heteroaryl bromides. A variety of heteroaromatics such as furans, thiophenes, pyridines, thiazoles or oxazole derivatives have been employed and moderate to good yields were generally obtained using the air-stable complex [PdCl(dppb)(C3H5)] as catalyst. A range of functions such as acetyl, formyl, ester or nitrile on the heteroaromatics is tolerated. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
