Abstract

The coordination chemistry of a family of hybrid P,E ligands of the type, o-C₆H₄(CH₂PBu^t₂)(CH₂E) (E = SBu^t (1), S(=O)Bu^t (2), NMe₂ (3)), with Pt(II) and Pt(0) precursors has been investigated. Both monodentate and chelating bonding modes were observed, along with a number of examples of hemilabile behaviour. Chelated [PtCl₂(P,S)] and [PtCl₂(P,N)] complexes have been synthesised, and unusual reactivity between [PtCl₂(1,5-hexadiene)] and ligand 2 or 3 has been observed, resulting in σ:η²-bound phosphonium complexes. Three [PtH₂(P,E)₂] complexes were prepared, and in the case of ligand 1, derivatised to a number of [PtHL(P,S)₂]CH(SO₂CF₃)₂ complexes (L = CO, NCMe, 1,3,5-triaza-7-phosphaadamantane). One of these complexes, [PtH(NCMe)(P,S)₂]CH(SO₂CF₃)₂, undergoes reversible dissociation of MeCN resulting in chelation of one of the P,S ligands. Reactions with Pt(0) precursor complexes resulted in the first examples of chelated [Pt(alkene)(P,S)] and [Pt(alkene)(P,S=O)] complexes, and 14-electron [Pt(P,E)₂] complexes of all three ligands.

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
