Co-ordination compounds of indium. Part 47. Indium(I) and thallium(I) derivatives of alkanedithiols

Abstract

The electrochemical oxidation of anodic indium in non-aqueous solutions of a series of C&i q, ) gives the unusual indium(i) compounds In[SR(SH)], containing the alkanethiol(thio1ato) ligand. These compounds can be deprotonated by either NEt, or NBun40H to form salts of the [Inl(S,R)] -anion; this anionic complex can be oxidized b y I, to the corresponding indium(iii) species [Inllll,(S,R)] -, which can also be produced by successive I , oxidation and deprotonation of In ' [SR(SH)]. Reaction with the o-quinones 0-X4C60, gives the catecholato derivatives [In~11{SR(SH)}(0,C6X4-o)] (X = CI or Br). Carbon disulphide insertion occurs at only one In-S bond. With thallium, the products of electrochemical oxidation are TI,(S,R) in all the cases studied.

The use of sacrificial anodes for the electrochemical synthesis of metallic complexes

“…acetonitrile solutions of alkanedithiols, R(SH) 2 , under a dry nitrogen atmosphere were also reported [243].…”

DC Electrical Conductivity of the Direct Electrochemically Synthesized Polythiophene Metal Complexes

“…Electrochemical synthesis of the thiophene derivative metal complexes was carried out according to the literature (13).…”

The direct electrochemical synthesis of d10 metal ion derivatives of some anionic bidentate oxygen donors

“…The method of preparing these new compounds was essentially the same as those used in our previous papers (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). The solution phase was contained in a 100 mL round-bottomed flask with a Schlenk arm; a metal rod suspended through rubber septum formed the anode of the cell, and a platinum wire was the cathode.…”

“…The isolation of the indium(II1) flavonate can be explained in terms of the initial formation of an indium(1) species electrochemically, followed by disproportionation according to the stoichiometry [4] 31n(Cl5H9O3) + 21n + In(C15H903) 3 In keeping with this argument, during the initial stages'of the electrolysis we observed the formation of a yellow solid, which quickly decomposes shortly after its formation with the deposition of metallic indium, which can be isolated in the quantity required by the stoichiometry of reaction [4].…”
