Synthesis and characterisation of mono- and binuclear palladium and platinum complexes with organochalcogenides
摘要:
Mononuclear palladium and platinum complexes of the type M(ER)(2)((PP)-P-boolean AND) [M = Pd or Pt; ER = SPh, SC6H4Cl-4, SC6H4Me-4, SC6F5, SePh, TeC6H4OEt-4; (PP)-P-boolean AND = dppm or dppe] have been prepared and their ability to form dinuclear metal species has been demonstrated. All complexes have been characterised by multinuclear magnetic resonance (H-1, C-13, Se-77, Pt-195) spectral data. The effects of phosphine ligands and organochalcogenides are reflected in the Se-77 and Pt-195 NMR shifts. The shielding of Pt-195 NMR chemical shifts has been interpreted in terms of their binding ability to platinum. The structures of two derivatives, namely [Pd(SC6F5)(2)(dppe)] and [Pd(SePh)(2)(dppe)], have been established by X-ray crystallography. The palladium atom in each of the monomeric structures exists in a square planar geometry. (C) 1999 Elsevier Science S.A. All rights reserved.

The first definitive evidence of insertion of an alkyne into an S-Pd bond has been presented. The reaction of Pd(SAr)2(DPPE) with dimethylacetylenedicarboxylate (DMAD) gave the cis-insertion product (Z)-Pd-[C(CO2Me)=C(SAr)(CO2Me)](SAr)(DPPE), whose structure was unambiguously determined by X-ray crystallographic analysis.
已经提出了炔烃插入 S-Pd 键的第一个明确证据。Pd(SAr)2(DPPE)与乙炔二羧酸二甲酯(DMAD)反应得到顺式插入产物(Z)-Pd-[C(CO2Me)=C(SAr)(CO2Me)](SAr)(DPPE),其结构由 X 射线晶体学分析明确确定。

(Phenylalkyl)palladium Complexes Containing β-Hydrogen Atoms: Synthesis and Characterization of [PdR2(dppe)], [PdR(SPh)(dppe)] (R = CH2CH2Ph, CH2CH2CH2Ph, CH2CHMePh), and [Pd(CH2CH2CH2Ph)X(dppe)] (X = I, Br, Cl)
Synthesis and characterization of heterodinuclear thiolate complexes containing the Pd(η3-allyl)+ moiety. Crystal structure of [(dppe)Pd(μ-SC6H4Me-p)2Pd(η3-C3H5)][ClO4]
Hetero dinuclear complexes of the types [(dppe)M(mu-SR)(2)Pd(eta(3)-allyl)][ClO4] (M = Pd or Pt) and [(dppe)Pt(mu-SC2H4S)Pd(eta(3)-allyl)][ClO4] [dppe = 1,2-bis(diphenylphosphino)ethane; allyl = C3H5 or C4H7] have been obtained by reaction of the corresponding cis-dithiolato complexes, [M(SR)(2) (dppe)] or [Pt(SC2H4S)(dppe)]. and [Pd(eta(3)-allyl)(PhCN)(2)][ClO4]. The identity of these complexes has been established by NMR (H-1 and P-31) spectroscopy. The crystal structure of [(dppe)Pd(mu-SC6H4Me-p)(2)Pd(eta(3)-C3H5)][ClO4] has been determined by single-crystal X-ray methods. The p-tolyl groups on the sulfur atoms adopt a syn conformation with respect to the central Pd-S-2-Pd core. (C) 2000 Elsevier Science Ltd. All rights reserved.
