Platinum(II) derivatives of the tridentate ligand Ph2PCH2CH2P(Ph)CH2CH2PPh2 (triphos), including [Pt(SRF)(triphos)](CF3SO3) RF = C6F4CF3-4 1, C6F5 2, C6HF4-4 3, C6H4CF3-4 4, C6H3F2-2,4 5, C6H4F-2 6, C6H4F-4 7 and C6H5 8, have been prepared and characterised. 1H, 19F and 31P solution NMR has been used to evaluate the cis and trans influences of the fluorinated and non-fluorinated benzothiolate ligands, particularly through the cis and trans 1JPt-P values. The crystal and molecular structures of [Pt(SC6F4CF3-4)(triphos)](CF3SO3) 1, with a perfluorinated thiolate ligand, [Pt(SC6HF4-4)(triphos)](CF3SO3) 3, having a fluorinated thiolate, and [Pt(SC6H5)(triphos)](CF3SO3) 8, bearing a non-fluorinated moiety, are discussed as examples of extreme electronegativities.

The electrochemical oxidation of anodic indium in acetonitrile solutions of thiols RSH (R = C2H5, n-C4H9, C(CH3)2C2H5, C6H5, 2-C10H7, C6F5) has been shown to give thiolato derivatives of indium(I), -(II), or -(III), depending on R and on the experimental conditions. With R = C2H5 or n-C4H9, electrolysis in the absence of oxygen gives the hitherto unreported InSR compounds, while, with R = C5H11 or 2-C10H7, the products are In(SR)2, formulated as the In-In-bonded In2(SR)4. Arenethiols yield In(SR)3, and products of this stoichiometry are always obtained in the presence of oxygen. The structures of these compounds are discussed, as are the reactions of the indium(I) and -(II) species with iodine and certain other oxidizing agents. Corresponding reactions with thallium anodes gave T1SR for all R studied (C6H5, C6H4CH3-o, C6H4CH3-m, 2-C10H7).
Substitution Reactions of Thallous Thiophenoxide and Thallous Phenylselenide with Halogen-Bearing Substrates
Detty, Michael R.,Wood, Gary P.
, p. 80 - 89 (2007/10/02)
Thallous thiophenoxide (1) and thallous selenide (2) were prepared by the action of either thallous ethoxide or thallous pentoxide on thiophenol and benzeneselenol.The reagents 1 and 2 reacted readily with aroyl and acyl halides, imidoyl chlorides, α-halo ketones, α-halo esters, α-halo lactones, α-halo carboxylic acids, allyl halides, alkyl halides, chlorotrimethylsilane, chloroacetonitrile, and N-chlorosuccinimide to give substitution products and varying amounts of diphenyl disulfide and diphenyl diselenide.The reactions were run as heterogeneous mixtures in ether.The origin of the diphenyl disulfide and diphenyl diselenide was homolytic cleavage of the thallium-sulfur or thallium-selenium bond, on the basis of the products derived from the reactions of N-chlorosuccinimide with 1 and 2.
