Silver(i) nitrate was purchased from Lachema (Czech Republic), dimethyl sulfoxide (DMSO), palladium(ii) acetate (Pd(OAc)₂) and 3-bromopyridine from Sigma-Aldrich Chemie, 2-bromopyridine, diisopropyl phosphite and N,N-diisopropylethylamine from Fluka, 1,1′-bis(diphenylphosphino)ferrocene (dppf) from Alfa Aesar, bromotrimethylsilane from Acros, dichloromethane, methanol and acetonitrile from VWR Chemicals.

Solvents were purified by standard methods before use [25 ]. The 4,4,5,5-tetramethyl-1,3,2-dioxaphospholane 2-oxide was purchased from TCI Chemicals (TCI Europe N. V.- Tokyo Chemical Industry, Brussels, Belgium). All bromoalkenes, 1,8-dibromooctane, bithiophene, and tetrakis(triphenylphosphine)palladium (0) (Pd(PPh₃)₄) were purchased from Fluorochem. n-Butyllithium (1.6 M solution in hexane), Karstedt′s catalyst and chlorodimethylsilane were purchased from Sigma Aldrich (Merck, KGaA, Darmstadt, Germany), and bromotrimethylsilane was purchased from Acros Organics (Thermo Fisher Scientific, Geel, Belgium). All chemicals were used as purchased without further purification. Thin-layer chromatography was performed on Merck TLC plates of silica gel 60, F-254, visualization under UV 254 nm and 365 nm, for column chromatography was used silica gel 60 (Merck).
