Chiral Cyclopentadienyl Cobalt(III) Complexes Enable Highly Enantioselective 3d-Metal-Catalyzed C-H Functionalizations

Nicolai Cramer, Yun-Suk Jang, Kristers Ozols

The synthesis of a set of cobalt(III)-complexes equipped with trisubstituted chiral cyclopentadienyl ligands is reported, and their steric and electronic parameters are mapped. The application potential of these complexes for asymmetric C-H functionalizati ...

Access to P- and Axially Chiral Biaryl Phosphine Oxides by Enantioselective (CpIrIII)-Ir-x-Catalyzed C-H Arylations

Nicolai Cramer, Julia Pedroni, Yun-Suk Jang

An enantioselective C-H arylation of phosphine oxides with o-quinone diazides catalyzed by an iridium(III) complex bearing an atropchiral cyclopentadienyl (Cp-x) ligand and phthaloyl tert-leucine as co-catalyst is reported. The method allows access to a) P ...

Cooperative Effects between Chiral Cp-x-Iridium(III) Catalysts and Chiral Carboxylic Acids in Enantioselective C-H Amidations of Phosphine Oxides

Nicolai Cramer, Yun-Suk Jang, Michael Christian Dieckmann

An enantioselective C-H amidation of phosphine oxides by using an iridium(III) catalyst bearing an atropchiral cyclopentadienyl (Cp-x) ligand is reported. A very strong cooperative effect between the chiral Cp-x ligand and a phthaloyl tert-leucine enabled ...

Chiral Cyclopentadienyl Iridium(III) Complexes Promote Enantioselective Cycloisomerizations Giving Fused Cyclopropanes

Nicolai Cramer, Yun-Suk Jang, Michael Christian Dieckmann

The cyclopentadienyl (Cp) group is a very important ligand for many transition-metal complexes which have been applied in catalysis. The availability of chiral cyclopentadienyl ligands (Cp-x) lags behind other ligand classes, thus hampering the investigati ...
