Extended heterocyclic systems 2. The synthesis and characterisation of (2-furyl)pyridines, (2-thienyl)pyridines, and furan-pyridine and thiophene-pyridine oligomers

The Stetter procedure has been adapted to produce simple 2-furyl- and 2-thienyl-pyridines and their related oligomers, which have been characterised by 13C NMR spectroscopy. σ values for the 2-furyl and 2-thienyl rings have been deduced from the pK(a) values of the conjugate acids of the 2-furyl- and 2-thienylpyridines.

Direct C-H arylation of thiophenes at low catalyst loading of a phosphine-free bis(alkoxo)palladium complex

An efficient phosphine-free direct C-H arylation of thiophenes at the α-position has been developed at low catalyst loading of bis(alkoxo)palladium complex (Cat.I, 0.1-0.2 mol %). The developed synthetic method can be applied to the synthesis of α-aryl/heteroaryl thiophenes from aryl or heteroaryl bromides in good to excellent yields and is compatible with the substrates bearing electron-donating or electron-withdrawing groups. The reactivities of the 2- and 5-positions of thiophenes are equivalent and not dependent on steric hindrance under optimal conditions. This condition can also be applied to other heterocyclic moieties such as benzothiophene, benzofuran, and pyrrole with high conversion yields.

Efficient Pd-catalyzed direct arylations of heterocycles with unreactive and hindered aryl chlorides
