- Abstract
The thermal behavior of some new organotellurium compounds, based on di(cyclohexylmethyl) telluride [i.e., (CHCH)Te(R)X: R, X = I, I ( 1); Br, Br ( 2); CH, I ( 3); CHCH, Br ( 4); CH, BPh ( 5); CH BPh ( 6)] studied by thermogravimetric analysis. The organic moieties of compounds 1 and 2 were completely vaporized at 212 and 258 °C, respectively, leading to the deposition tellurium metal. Compounds 3 and 4 decomposed in two stages, losing RX in the first stage and depositing tellurium metal with formation of volatile 1,2-dicyclohexylethane in the second stage. Mass spectra of compounds 1, 2, 3 and 4 indicate the formation of 1,2-dicyclohexylethane and the association of compounds 2 and 3 in the gas phase. Oxoborinic acid (HBO) is the residual product for the thermal decomposition of compounds 5 and 6 at 228 and 250 °C, respectively. No BTe was formed during the thermolysis of these two compounds. Mechanisms for the decomposition of all compounds were proposed and discussed.
