Direct arylation of heteroaromatic compounds with congested, functionalised aryl bromides at low palladium/triphosphane catalyst loading

A new ferrocenyl triphosphane ligand associated to palladium was found to be an efficient catalyst for the direct coupling of highly congested, functionalised aryl bromides with a variety of heteroarenes. These coupling reactions can generally be performe

Alkylated 2,2′-bithiophenes and 2-phenylthiophenes in the composition of pyrolysis products of high-sulfur kerogen

Compounds from the 5-n-alkyl-2,2′-bithiophene, 5-n-alkyl-5′- methyl-2,2′-bithiophene, 5-n-alkyl-2-phenylthiophene, and 5-n-alkyl-2-o-tolylthiophene homologous series were synthesized to prove their presence in the pyrolysis products of sulfur-rich kerogen. A study of the pyrolysis products of sulfur-vulcanized polybutadiene confirmed that these compounds can be formed via the thermal transformation of n-alkyl polysulfur-bound fragments of sulfur-rich kerogen. The earlier proposed scheme that assumes the dependence of the composition of the pyrolysis products of sulfur-rich kerogen on its saturation with sulfide bridges was experimentally corroborated.
