New copper(I) derivatives of organotellurium compounds: Synthesis, vibrational and 125Te Mössbauer spectra

Synthesis and reactions of organic compounds containing bonds of Te to Group 14 elements

“…Thus the reaction of phenyl triphenylgermyl(stannyl) tellurides 1e,i with the palladium(II) chloride ± benzonitrile complex results in elimination of Ph 3 ECl followed by the formation of red-brown palladium tellurolates 21 which seem to possess polymeric structures. 4 The reaction of compounds 1 with CuCl in chloroform 4 or acetonitrile 41 gives polymeric copper(I) tellurolates 22.…”

Stable tellurols and their metal derivatives

“…Of copper, silver and gold tellurolates, only Cu(I) tellurolates which do not contain bulky organic radicals at the Te atom have been described previously. These compounds were prepared by the exchange reactions of sodium tellurolates with CuCl 84,85 or by the reactions of CuCl with triphenylstannyl tellurides 38a ± e. 85,86 M = Mn: n = 1, L = DMPE (34a, 79%);…”

“…87 The tellurolates 39a ± d are brown insoluble powders, which have apparently the polymeric structures. 85,86 Attempts to prepare Cu(I) and Ag(I) tellurolates with bulky organic radicals by the exchange reactions of metal chlorides with lithium tellurolate 5a have been unsuccessful. 59 Since tris(trimethylsilyl)silanetellurolate 5a is a stronger reducing agent than the usual lithium and sodium tellurolates, it is readily oxidised by Cu(I) and Ag(I) chlorides to the ditelluride 7.…”
