Abstract
The first synthesis of 3,4'-dibromo-2,2'-bithiophene via metal-catalysed cross-coupling between a metallated and a halogenated thiophene derivative is described. An X-ray crystal structure of 3,4'-dibromo-2,2'-bithiophene is reported, 3,4'-Dibromo-2,2'-bithiophene was converted into corresponding bis(alkylsulfanyl) derivatives through bromine-lithium exchange, followed by reaction with two dialkyl disulfides (Me2S2 or Bu2S2). The H-1 and C-13 NMR data are discussed.
