N-Sulfinylcarboximidates as a New Class of Chiral Bidentate Ligands: Application to Asymmetric Coordination Chemistry

N-Sulfinylcarboximidates as a New Class of Chiral Bidentate Ligands: Application to Asymmetric Coordination Chemistry:

A class of its own: A new chiral bidentate ligand, N-acetyl-tert-butanesulfinamide, was applied to the asymmetric synthesis of octahedral ruthenium polypyridyl complexes. This new class of ligands coordinates in a bidentate fashion through its deprotonated N-sulfinylcarboximidate form (see scheme). This sulfinamide auxiliary should be highly valuable for the efficient asymmetric synthesis of a large variety of ruthenium complexes.
