Ring opening reactions of [M(CO)3(η1-Ph2PCH2PPh2)(η2-Ph2PCH2PPh2)] M = Cr, Mo, or W with Rh or Ir complexes to give bimetallic systems: synthesis of [(OC)3Mo(µ-Ph2PNHPPh2)2RhCl(CO)]

Abstract

Complexes of the type [(OC)₃M(µ-Ph₂PCH₂PPh₂)₂M′X(CO)] or [(OC)₃M(µ-Ph₂PCH₂PPh₂)₂M′(CO)₂]⁺PF₆^– have been made either as described in the title or by a ring opening reaction of [M′(CO)(η²-Ph₂PCH₂PPh₂)₂]Cl (M′= Rh or Ir) with a labile Cr, Mo, or W carbonyl derivative: the first bimetallic complex of Ph₂PNHPPh₂ is described.
