Synthesis of a new type of alkene metal complex using face-capping thione-alkene ligands†
Abstract
A series of complexes of novel chelating thione-alkene S(η2-CC)S tridentate ligands bound to late transition metals (Ir, Rh, Pd) were isolated and characterised. Counter-anions play an important role in the binding of the alkene moiety to the metals. Different solvents were observed to affect the stability of the rhodium complexes.
