The new conformational rigid spiro phosphinooxazolines 1 were synthesized from 7-bromo-1-indanone. The asymmetric catalytic potential of them was demonstrated in the asymmetric palladium catalyzed allylic amination. High yields and enantioselectiviti

Enantiomerically pure 2-[2-(diphenylphosphino)aryl]oxazolines are readily prepared from 2-bromobenzonitrile by transmetalation with BuLi, subsequent reaction with chloro-diphenylphosphine and conversion of the resulting phosphinoaryl nitrile to the o

New phosphinooxazoline (PHOX) η 5 -indenyl complexes of iron were synthesized and applied as catalysts in the Mukaiyama aldol reaction. Reaction of three different PHOX ligands with [Fe(η 5 -Ind)I(CO) 2 ] afforded the iodide salts of three complexe

The study describes the first catalytic application of iron phosphinooxazoline complexes and Fe(OTf)2 in oxidation reactions. New iron phosphinooxazoline (PHOX) complexes of the general formulation [Fe(PHOX)2]2+[OTf]2 (3, OTf = CF3SO3−) were synthe

Efficient calculation of the properties of metal-containing complexes relevant to catalysis is of major interest for better characterizing and optimizing the catalysts. For this, a new force field, called VALBOND-TRANS here, is proposed. It is based

A family of chiral phosphinooxazolines (12a–e) derived from modular, enantiopure β-amino alcohols has been prepared, and their palladium complexes have been used as chiral mediators in the asymmetric allylic alkylation reaction. The oxazoline moie

Novel phosphinooxazolines, containing a unit of central and a unit of planar chirality in a matched case combination, have been successfully tested in the Pd-catalyzed asymmetric allylic substitution with cycloalkenyl acetates as substrates.
