Reactivity of tetra-n-butylammonium di-µ-chloro-bis[bis(pentafluorophenyl)palladate(II)]. A general method for the synthesis of cis isomers of neutral and anionic palladium(II) complexes

Abstract
The reaction of [NBun 4]2[Pd2(µ-Cl)2(C6F5)4] with L (L = N, P, As, or Sb donor ligand) leads to the synthesis of novel anionic palladium complexes of the type [NBun 4][PdCl(C6F5)2L], which react with L to give the neutral complexes [Pd(C6F5)2L2]. Both families of compounds are the cis derivatives. Moreover, replacement of Cl by SCN or CN, and of L (SbPh3 or AsPh3) by PPh3, takes place without a change in configuration, giving again cis isomers.
