Abstract

Single crystal X-ray diffraction analysis of Pd(O2CCF2CF3-O)2(dppf) 1 shows that one of the two unidentate fluoropropanoates shows a rare bonding behavior with significant π character for the C[double bond, length as m-dash]Ocoord bond whereas the C–Opendant bond is long and bears a basic function. Complex 1 serves as a metalloligand towards AgO2CCF2CF3 to give PdAg(μ-O2CCF2CF3)2(O2CCF2CF3-O)(dppf) 2, which is fluxional in solution showing interchanges of the bridging and unidentate fluoropropanoate groups. Being an unusually stable Pd(II) carboxylate, 1 also serves an effective entry to mixed-metal carboxylates.
