Einfache Synthese von (η²‐Ethen)bis(triphenylphosphan)platin(0)

Abstract

Simple Synthesis of (I*-Ethene)bis(triphenylphosphane)platinum(O)The title compound 2 is easily accessible through reduction of dichlorobis(tripheny1phosphane)-platinum(I1) (1) with sodium tetrahydridoborate in ethanol under ethene pressure or without pressure in methylene chloride/ethanol. No nitrogen atmosphere or purified solvents are necessary.

Complexation of cage thiones with bisphosphine platinum(0) complexes

“…2, 4 [15], 3 [5], 12 [16], platinum(0) complexes 8 [17], and 10 [18] were prepared as described in the literature. NMR spectra were recorded on a Brucker DRX 200 spectrometer.…”

Molecular Structure and Dynamics of 1,3-Distanna-2-Platina[3]Ferrocenophanes

“…Materials: Hexamethyldistannane 2 was used as a commercial product, and the other starting materials such as 1, [14] 3, [12a] and 4 [15,16] were prepared following literature procedures. The bis(triphenylphosphane)platinum complexes 5 a [2] and 6 a [5] had been obtained before from the reaction of 1 with 2 and 3, respectively.…”

Synthesis and analytical characterization of novel pyridyl‐substituted 1,1′‐ethenedithiolato complexes

“…The C O signals appear at about δ = 186.0-193.5 and are shifted downfield in contrast to those in the uncoordinated dithioacids [7,[9][10][11]. Table 3 illustrates the different 13 C NMR signals and the coupling constants of the methine carbon atom.…”

“…The starting products were used without previous purification and the following metal salts were prepared according to the literature procedures: (Ph 3 P) 2 PtCl 2 [13], (Et 3 P) 2 PtCl 2 [14], dppePtCl 2 [15], (Ph 3 P) 2 PdCl 2 [16], dppePdCl 2 , and dppeNiCl 2 [17].…”
