ABSTRACT

Reaction of [Ru2(CO)6(µ-PFu2)(µ-η1,η2-Fu)] (Fu = furyl) 1 with tri(2-furyl)phosphine under thermal conditions produces simple mono- and disubstitution products [Ru2(CO)5(PFu3)(µ-PFu2)(µ-η1,η2-Fu)] 2a and [Ru2(CO)4(PFu3)2(μ- PFu2)(µ-η1,η2-Fu)] 2b. Both complexes were fully characterized by spectroscopic and analytical methods and the molecular structures of 2a and 2b were established by X-ray crystallography. The Ru-Ru edge bridged by the µ-η1,η2-bound PFu2 fragment remains intact after the substitution reaction. The product yields of both complexes depend on the stoichiometry of the reactants. All of these new diruthenium complexes are electron precise with 34 cluster valence electrons.
