Palabras clave: iridium hydrogenation P-S ligands
Resumen: A family of 12 modular ferrocenyl planar chiral phosphine-thioethers (P,S) has been studied in the
asymmetric hydrogenation ofminimally functionalized alkenes. These ligands differ by the substituent on
sulfur or by the linker between the ferrocene moiety and the sulfur atom (no linker, methylene or methyl
substituted methylene linker bearing an additional element of chirality). The cationic iridium(cod)
complexes of the different P,S ligands have been efficiently synthesized. For the majority of the ligands,
coordination yielded only a single diastereoisomer with full control of the absolute configuration on sulfur.
The different iridium complexes have been used in the hydrogenation of various di, tri, and tetrasubstituted
minimally functionalized olefins. Conversions and enantioselectivities are highly dependent on
the ligand and substrate structure. Full conversions and low-to-excellent enantioselectivities could be
obtained (maximum ee from 14 to 94% for 1,1-disubsituted alkenes, from 17 to 99% for trisubstituted
olefins, and 34% for the tetrasubstituted alkene)
