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. © 2009 Verlag der Zeitschrift für Naturforschung, Tübingen.
