摘要：

A general method for the syntheses of dipalladium compounds having a singly bonded Pd26+ core and the formula R,S-cis-Pd2(C6H4PPh2)2(O2CR)2Cl2 is described. When the alkyl group in the carboxylate ligands is an electron donating group, the compounds are stable and the yields high. The Pd-Pd distances for the diamagnetic compounds with R = CF2 and CMe3 are 2.5434(4) and 2.5241(9) Å, respectively. Calculations at the DFT level suggest that the electronic configuration is σ2π4δ2δ*2π*2. These represent rare examples of palladium(III) compounds. Copyright © 2006 American Chemical Society.
