“…As a preliminary study on the reactivity of the complexes, the charge-transfer (CT) complex of (dppf)Pt(TFBT) 2 was prepared by reacting it with F4TCNQ (2,3,5,7,8, in CH 2 Cl 2 /CH 3 CN, giving a species with composition [(dppf)Pt(TFBT) 2 ] 3 (F4TCNQ) 2 as indicated by elemental analysis data [22]. The UV-Vis spectra of the CT complex in CH 2 Cl 2 show a red-shift of two intense absorption peaks of a neutral F4TCNQ appearing at 394 and 372 nm to 458 nm [23] (see Fig.…”

“…The more-electronegative TFBT ligand induces a short Pt-P bond distance (2.273(2) Å), a large Pt-P coupling constant (J Pt-P = 3171 Hz) and a high oxidation potential (E 3 pa ¼ 1:355 V). A charge-transfer complex of (dppf)Pt(DMBT) 2 was prepared by the reaction with F4TCNQ and characterized.Ó 2009 Elsevier B.V.

“…1) [15] shows that the two TFBT ligands are in an anti-conformation with respect to the P 2 PtS 2 plane, as in many metal complexes with a fluorinated benzenethiolate ligand [2][3][4][5]. Two TFBT ligands are parallel with the dihedral angle of 15.2(1)°, which is somewhat larger than that found in (dppf)Pt(SC 6 F 5 ) 2 (2.7(2)°and 9.8(3)°) [2] and (dppe)-Ni(SC 6 F 5 ) 2 (4.9°) [5].…”

Cationic PtII–IrIII heterobimetallic complexes bridged by cyclooctane‐1,2‐dithiolato ligands [(PPh3)2Pt(μ2‐SRS)IrCl(η5‐Cp*)][SbF6] [R = cis‐C8H14 (5), trans‐C8H14 (6), Cp* = C5Me5] were synthesized by reaction of (cyclooctane‐1,2‐dithiolato)PtII complexes [Pt(SRS)(PPh3)2] [R = cis‐C8H14 (3), trans‐C8H14 (4)] with [IrCl(μ‐Cl)(η5‐Cp*)]2 in thf in the presence of AgSbF6. The structures of complexes 5 and 6 were fully characterized by their NMR spectroscopic data. Moreover, X‐ray crystallographic analysis of 5 revealed that the PtS2Ir core exhibits a hinged arrangement, in which the cis‐cyclooctane‐1,2‐dithiolate acts as a bridging ligand between the platinum and iridium metals. Complexes 5 and 6 served as a catalyst in the hydrosilylation of terminal alkynes R′CCH (R′ = Ph, Bu, CO2Me) with tertiary hydrosilanes such as Et3SiH and Ph3SiH to afford selectively β‐(Z)‐vinylsilanes 8 in high yields.

Substitution of the chloro ligands of cis‐[Pt(PEt3)2Cl2] by 4‐methylthio‐2‐thioxo‐1,3‐dithiole‐5‐thiolate (L) leads to the thiolato complexes trans‐[Pt(PEt3)2ClL] (2) and trans‐[Pt(PEt3)2L2] (1), which have been characterised by X‐ray crystallography. In the solid state, the square planar arrangement is capped by an endocyclic sulfur atom of L, which gives rise to distorted square‐pyramidal and pseudooctahedral geometries for 2 and 1, respectively. Complex 1 coexists in solution with [Pt(PEt3)(η1‐L)(η2‐L)] (3), which results from the reversible dissociation of one phosphane ligand. The combination of η1‐(thiolato) and η2‐(thiolato/thioether) L in 3 has been established by variable‐temperature 1H NMR spectroscopy and crystal structure determination. The η2‐coordination mode of L is also observed in cis‐[Pt(PEt3)2L]+ (4), which results from the abstraction of the chloro ligand of 2 by excess TlPF6. An S‐demethylation reaction occurs when 1 is heated in acetonitrile to yield the structurally‐characterised dithiolene complex [Pt(PEt3)2(dmit)] (5) (dmit2– = 2‐thioxo‐1,3‐dithiole‐4,5‐dithiolate) and MeL. Treatment of cis‐[Pt(PPh3)2Cl2] with 2 equiv. of L leads to a mixture of [Pt(PPh3)2(dmit)] (6) and [Pt(PPh3)(η1‐L)(η2‐L)] (7). Complex 7 predominates in solution over its parent compound,[Pt(PPh3)2L2]. The identification of CH3Cl by 1H NMR spectroscopy proves that [Pt(PPh3)2ClL] is involved as an intermediate in the demethylation process. The reaction of L with platinum precursors that are blocked in a cis arrangement by chelation of 1,1‐bis(diphenylphosphanyl)methane (dppm) and 1,1‐bis(diphenylphosphanyl)ethane (dppe) leads to the formation of the thiolato complexes cis‐[Pt(η2‐dppm)L2] (8) and cis‐[Pt(η2‐dppe)L2] (9). The solid‐state structure of 8 reveals the occurrence of an additional weak interaction between a thiomethyl group and the platinum centre (Pt–S 3.073 Å).
