TI  - Reversible Ligand Pairing and Sorting Processes Leading to Heteroligated 
      Palladium(II) Complexes with Hemilabile Ligands.

AB  - Halide-induced ligand pairing and sorting processes have been observed in the 
      context of Pd(II) complexes with hemilabile P,S and P,O ligands. Mixing of the 
      ligands Ph(2)PCH(2)CH(2)SMe (7) and Ph(2)PCH(2)CH(2)SPh (8) with a Pd(II) 
      precursor in CH(2)Cl(2) results in a mixture of [(7)(2)ClPd]Cl, [(8)(2)Cl(2)Pd], 
      and [(7)(8)ClPd]Cl complexes at 20  degrees C. This equilibrium can be driven toward the 
      heteroligated structure [(7)(8)ClPd]Cl by (1) cooling the mixture or (2) 
      precipitation with hexanes, leading to the exclusive formation of semiopen 
      heteroligated complex cis-[kappa (2)-(7)-kappa (1)-(8)ClPd]Cl (9a), as confirmed by a 
      single-crystal X-ray diffraction study and solid state CPMAS (31)P(1)H NMR 
      spectroscopy. Dissolution of 9a in CH(2)Cl(2) leads to the original mixture of 
      complexes, which illustrates the reversible nature of this ligand pairing and 
      sorting process. Similar processes occur when a combination of P,S and P,O 
      ligands is used. The semiopen heteroligated complexes can be chemically 
      manipulated in a reversible fashion to form closed complexes, allowing for 
      control of the relative position and flexibility between neighboring substituents 
      in these "tweezer"-like structures. Control experiments suggest these ligand 
      sorting and pairing processes occur via a halide-induced ligand rearrangement 
      (HILR) reaction.
