Article Synopsis
- A new library of diamidophosphite-sulfides, made from terpenoid 1,3-thioether alcohols, was created and shown to effectively complex with Pd(II) ions, forming various ligand bonding configurations.
- The study utilized 2D NMR spectroscopy and X-ray diffraction to determine the structures of the ligands and their metal complexes.
- The ligands achieved impressive enantioselectivity (ee) in several reactions, such as up to 95% ee in Pd-catalyzed asymmetric allylic substitutions and up to 90% ee in Rh-catalyzed asymmetric hydrogenation, with an analysis of how structural factors and reaction conditions influenced these results.
A series of easy-to-prepare and modular chiral ,-bidentate phosphoramidites were synthesized. With respect to Pd(II), these ligands showed the ability to form stable ,-chelate allylic complexes. The structures of the ligands and their complexes were confirmed by 2D NMR spectroscopy and single-crystal X-ray diffraction.

The reaction of these compounds with [Pd(allyl)Cl] in the presence of AgBF yielded complexes [Pd(allyl)(L)]BF. In addition, metallochelates [Pd(allyl)(L)]BF with (S)-methioninol-based P,S-bidentate ligands were prepared.
