Abstract

41-44Reactions of [PdCl2(PP)] (PP=dppe, dppp) with Pb(SMes)2 or NaEMes yield mononuclear complexes of the type,<span style="mso-bidi-font-weight: bold"> [Pd(EMes)2(PP)] (Mes = mesityl (2,4,6-Me3C6H2); E = S, Se or Te). However, in the reaction of [PdCl2(dppp)] with NaTeMes, a trinuclear complex, [Pd3(µ-Te)2(dppp)3]2+ is formed via Te-C bond cleavage in CH2Cl2. <span style="mso-bidi-font-weight: bold">These complexes have been characterized by elemental analyses and NMR (1H, 31P{1H}) spectroscopy. The molecular structure of [Pd(SeMes)2(dppe)] has been established by single crystal X-ray diffraction analysis.</span
