Dalton communications. Synthesis and structural characterisation of [Pd4(µ3-CH)(µ-Cl)3(PBut3)4]: a tetrahedral palladium cluster with a µ3-methylidyne ligand
摘要:
The compound [Pd-4(mu(3)-CH)(mu-Cl)(3)(PBu(3)(t))(4)] has been synthesised from [Pd-2(dba)(3)] (dba = dibenzylideneacetone), PBu(3)(t) and CHCl3 and characterised spectroscopically and by single-crystal X-ray analysis; it undergoes substitution reactions with Br- and tertiary phosphines and is a catalyst for the polymerisation of ethyne.
