Chiral Diarylamido (SO)-N-(SO) Sulfoxide Pincer Ligands

Only recently S-stereogenic sulfoxides have emerged as a versatile and encouraging novel class of ligands. Besides the proximity of the chiral information, located at the sulfur atom, to a ligated metal and thus to the reaction center, sulfoxides may switch between S and O coordination and bind to “hard” and “soft” metals, respectively. Combination of these attractive features of sulfoxides with the rigid, C2-symmetric, T-shaped configuration of a pincer scaffold leads to a promising ligand system for asymmetric catalysis.
