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 [RuCl&sub2;(PPh&sub3;)&sub3;] 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. Keywords: catalysis; cycloaddition; ferrocenyl ligands; hydrogen transfer.
