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 [NBuⁿ₄]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 [NBuⁿ₄][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.
