Dinuclear platinum complexes with designer thiolate ligands from the monoalkylation of [Pt₂(μ-S)₂(PPh₃)₄]
(Elsevier, 2010)Alkylation reactions of the nucleophilic platinum(II) sulfide complex [Pt₂(μ-S)₂(PPh₃)₄]with functionalised alkylating agents have been investigated as a versatile synthetic route to dinuclear, cationic sulfide-thiolate ... -
E/Z isomerism in monoalkylated derivatives of [Pt₂(μ-S)₂(PPh₃)₄] containing 2,4-dinitrophenylhydrazone substituents
(2011)Alkylation of [Pt₂(m-S)₂(PPh₃)₄] with 2,4-dinitrophenylhydrazone-functionalized alkylating agents XC6H4C{¼NNHC₆H₃(NO₂)₂}CH2Br (X¼H, Ph) gives monoalkylated cations [Pt₂(m-S){m-SCH₂C{¼NNHC₆H₃(NO₂)₂}C₆H₄X}(PPh₃)₄]⁺. An X-ray ... -
Further investigations on the methylation chemistry of [Pt₂(μ-S)₂(PPh₃)₄]
(Taylor & Francis, 2011)The methylation product of the reaction between [Pt₂(µ-S)₂(PPh₃)₄] and MeI in diethyl ether has been reinvestigated using positive-ion electrospray mass spectrometry and found to be contaminated with the dimethylated ... -
Further studies on the dialkylation chemistry of [Pt₂(μ-S)₂(PPh₃)₄] with activated alkyl halides RC(O)CH₂X (X = Cl, Br)
(Elsevier BV, 2011)Further studies have been carried out into the reactivity of [Pt₂(μ-S)₂(PPh₃)₄] towards a range of activated alkylating agents of the type RC(O)CH₂X (R = organic moiety e.g. phenyl, pyrenyl; X = Cl, Br). Alkylation of both ... -
Immobilization of [Pt₂(μ-S)₂(PPh₃)₄] on polymeric supports by sulfide alkylation and phosphine exchange reactions
(Taylor & Francis, 2013)The immobilization of the dinuclear platinum(II) sulfido complex [Pt₂(μ-S)₂ (PPh₃)₄] on solid supports has been investigated. Reaction with haloalkyl functionalized polymers [Merrifield's resin (chloromethylated polystyrene), ...
