Enantiomerically enriched 1,2-P,N-bidentate ferrocenyl ligands for 1,3-dipolar cycloaddition and transfer hydrogenation reactions

Novel complexes of 1,2-P,N-bidentate ferrocenyl ligands with AgOAc or with [RuCl₂(PPh₃)₃] as catalysts have been studied in asymmetric synthesis. The catalytic activity of these systems have been studied in [3+2]-cycloaddition of azomethine ylides with olefins and the asymmetric transfer hydrogenation of ketones.
