In this article, we describe two new platinum(II) complexes incorporating C2-symmetric enantiopure bis-sulfoxides ligands. The originality of these structures resides in the one-carbon tether between the two sulfoxide functions. X-ray structures show that coordination takes place through both sulfur atoms giving birth to intriguing platina-cyclobutane systems. We anticipate that these complexes should find uses in asymmetric catalysis.
