A number of diorganyl tellurides, including diaryl tellurides, diheteroaryl tellurides, and alkyl aryl and dialkyl tellurides, were found to catalyze the reaction of hydrogen peroxide with thiols.The thiol peroxidase activity of the compounds was assessed

The synthesis, isolation, and characterization of several alkali metal aryl tellurolates of general formula (2,4,6-R3C6H2)TeM(sol)n (R = Me, iPr, tBu; M = Li, Na, K; sol = THF, n = 1.33, 1.5, 2.5, 3; sol = DME, n = 1; sol = TMEDA, n = 1; sol = 18-crown-6, n = 1) is reported.Reduction of (2,4,6-Me3C6H2)2Te2 and (2,4,6-iPr3C6H2)2Te2 with 2 equiv of LiEt3BH in THF affords the corresponding lithium tellurolates 1 and 2.Direct Te insertion into the C-Li bond of (2,4,6-tBu3C6H2)Li(THF)3 in THF produces 3, while a similar reaction of Te metal with (o-C6H4CH2NMe2)Li affords the chelating tellurolate, 4.The action of Na/Hg amalgam on THF solutions of (2,4,6-Me3C6H2)2Te2 or (2,4,6-iPr3C6H2)2Te2 followed by work-up with TMEDA or DME leads to the sodium tellurolates 5 and 6 respectively.Treatment of THF solutions of (2,4,6-iPr3C6H2)2Te2 with 2 equiv. of KsBu3BH gives the polymeric tellurolate, (2,4,6-iPr3C6H2)2TeK(THF)1.33, (7).The infinite ladder-like structure is broken by reaction with 18-crown-6, which affords the monomeric derivative, 8.Reaction of 2 or 3 with THF suspensions of cis-(PPh3)2PtCl2 produces the air-stable cis-platinum tellurolates, 9 and 10, respectively.Reaction of 3 with trans-(PPh3)2Ir(CO)Cl, leads to the isolation of 11, a rare example of a Vaska's type complex with a cis-geometry, and only the second such structurally characterized derivative.Reaction of 4 with 1/2 equiv. of CdBr2 produces 12, Cd2.Compounds 3,4,7,10, and 11 have been characterized by single crystal X-ray diffraction.
