Reactions of low-valent metal complexes with fluorocarbons. Part VIII. Tetrakis(triphenylphosphine)- and tetrakis(methyldiphenylphosphine)-palladium

Abstract

The perfluorovinyl complex trans-(Ph₃P)₂Pd(CF:CF₂)Br is formed by treating tetrakis(triphenylphosphine)-palladium with bromotrifluorethylene. Analogous vinyl complexes trans-(Ph₂PMe)₂Pd(CF:CF₂)X (X = Cl or Br) are obtained from (Ph₂PMe)₄Pd and CF₂:CFX (X = Cl or Br). n-Heptafluoroiodopropane reacts with (Ph₂PMe)₄Pd to form trans-(Ph₂PMe)₂Pd(C₃F₇)l. n-Heptafluorobutyryl chloride reacts to form the acyl complex trans-(Ph₂PMe)₂Pd(COC₃F₇)Cl, whereas, pentafluorobenzoyl chloride affords trans-(Ph₂PMe)₂Pd(C₆F₅)Cl.
