1. Solventless and Mild Procedure to Prepare Organotellurium(IV) Compounds under Microwave Irradiation
Tellurium(IV) tetrachloride, p-methoxyphenyltellurium trichloride and the corresponding products of its reaction with alkynes were prepared under very mild reaction conditions, in absence of organic solvents and in short reaction times all assisted by microwave irradiation.

2. Teluretos vinÃlicos: reaÃÃes de acoplamento e investigaÃÃo da regio- e estereoquÃmica da hidroteluraÃÃo de alquinos
Vinylic tellurides are valuable synthetic intermediates and have recently been used in the total synthesis of many natural products. The hydrotelluration of alkynes is usually the method of choice to prepare Z-vinylic tellurides, in view of the easy access to the starting materials, the high regio- and stereoselectivity of the reaction and the practicality o

3. Novos aspectos e aplicações da química de teluranas e de teluretos orgânicos / New aspects and applications of the chemistry of organotelluranes and organic tellurides
The first part of this thesis deals with the study of the reactivity of electrophilic tellurium compounds, mainly tellurium tetrachloride and aromatic tellurium trichlorides. New aspects of the reactivity of TeCl4 towards alkynes and some acetophenones were disclosed. A mechanistic rationale for each of the processes studied was possible by the determination
