New palladium (II) complex of SCN unsymmetric pincer-type ligand via oxidative addition

A new approach to the synthesis of benzothiophene-based palladium(II) complex of SCN unsymmetrical pincer-type ligand from iodocyclization of bis(methylthio)phenyl substituted ethynyl pyridine followed by oxidative addition of tris(dibenzyledeneacetone)dipalladium(0) has been developed. The mechanistic implication of palladium complex reveals the practical evidence of oxidative addition step in Suzuki coupling reaction.
