Abstract

The synthesis of the new bis[2-(diphenylphosphino)ethyl](hydroxymethyl)phosphine tridentate ligand L^CH2OH/Ph is reported. The ligand reacts with [Pd(Cl)₂(PhCN)₂] to form [Pd(L^CH2OH/Ph)Cl]Cl. Exchange of the chloride ions for triflate (OTf^-) using AgOTf yielded pure [Pd(L^CH2OH/Ph)OTf]OTf. In addition to spectral characterization, the free ligand, L^CH2OH/Ph, and the Pd^II complex, [Pd(L^CH2OH/Ph)OTf]OTf, were structurally characterized. The synthesis of the Triphos ligand derivative L^CH2OH/Ph is reported, along with the corresponding Pd^II complex. In addition to spectral characterization of the free ligand and Pd^II complex, structural characterization is reported for [Pd(L^CH2OH/Ph)OTf]OTf.
