P‐Chirogenic Triazole‐Based Phosphine: Synthesis, Coordination Chemistry, and Asymmetric Catalysis

Herein we report the synthesis of a new P-chirogenic triazole-based phosphine according to the ephedrine methodology. Upon reaction with late transition-metal derivatives, Rh(I)and Pd-II, phosphine-triazole forms complexes with bidentate P,N coordination, as demonstrated by spectroscopic and X-ray crystallographic analyses. First experiments in asymmetric catalysis showed the catalytic potential of this new chiral P,N-type ligand.
