Synthetic Access to a Novel Binaphthyl Ligand Bearing a Phosphine and a Triazole Donor Site

Abstract

The combination of a diphenylphospinyl and a triazol-3-yl unit was realized for the first time at a 1,1'-binaphthyl backbone. This novel type of P,N-ligand is accessible as an enantiomerically pure compound in just a few steps. First experiments on the coordination chemistry with palladium(II) chloride have been carried out. A series of intermediates and a binuclear palladium(II) complex could be characterized by X-ray crystal structure analysis
