Opis

A general survey of oxidative insertion reactions of metals into Carbon halogen bond of organic halides together with an overview of the relevant work in case of elemental tellurium described in the literature is presented in Chapter 1. In Chapter 2 describes details of the chemicals used, preparation of the precursors, general experimental procedures wherever pertinent and characterization techniques used to determine molecular stoichiometry and structure of the newly synthesized compounds. In Chapter 3 deals with our efforts to explore single-step method of obtaining functionalized diorganotellurium(IV) dihalides directly from an organic halide and the element. Besides the expected facile oxidative insertion of Te(0) into Csp3-I bond of the acylmethyl iodides to afford carbonyl functionalized diorganotellurium(IV) diiodides, alp-bromoketones that a bear t-butyl or mesityl group with pronounced +I and steric effects, also added oxidatively to elemental tellurium even at room temperature and provided a direct synthetic route to obtain symmetrical diorganotellurium(IV) dibromides in almost quantitative yields.
