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 ...
