Synthesis and crystal structure of [Ru2(CO)6(µ-PPh2)(µ-PCHCHC6H4)], a complex with an unprecedented phospha-bicyclic ligand, obtained from [Ru3(µ-H)(CO)8(Ph2PCHCH2)(µ3-Ph2PCHCH)]via reductive elimination reactions

Abstract

The complex [Ru₂(CO)₆(µ-PPh₂)(µ-[graphic omitted]H₄)] has been obtained by thermal treatment of [Ru₃(µ-H)(CO)₈(Ph₂PCHCH₂)(µ₃-Ph₂PCHCH)]via reductive elimination of ethylene and benzene and metal–metal cleavage. The heterocyclic [graphic omitted]H₄ bridging ligand, obtained upon activation of co-ordinated diphenyl(vinyl)phosphine, is unprecedented. The complex has been identified by spectroscopic methods and its structure fully elucidated by X-ray diffraction methods.
