[EN] A series of C2 symmetrical 1:2 Ni:L complexes derived from a-amino amides were studied for the enantioselective addition of dialkylzinc reagents to aldehydes. Different structural elements on the ligands seem to play ...

[EN] Achieving dual stereocontrol in asymmetric reactions using a single enantiomer for the building of the
chiral catalyst or auxiliary is a very important goal in enantioselective synthesis as it eliminates the need for ...

Ni2+ complexes derived from simple -amino amides catalyze very efficiently the addition of Et2Zn to benzaldehyde, giving (S)-1-phenylethanol as the major isomer in most cases (94% yield, 97% ee for R=Bn). The nature of ...
[EN] A series of polymer-supported -amino amides derived from natural amino acids have been easily syn-thesized and fully characterized. Their chiral Zn (II) complexes catalyzed the enantioselective additionof diethylzinc ...
[EN] Different crosslinked polystyrene resins containing ionic liquid fragments covalently attached (supported ionic liquid-like phases: SILLPs) have been prepared and their conductivity has been studied by means of ...
