1. AplicaÃÃes de reagentes quirais de enxofre em catÃlise assimÃtrica e na sÃntese estereosseletiva de cetonas cÃclicas substituÃdas
This thesis describes the development of new methodologies for the use of chiral sulfur compounds, exploring their ability to transfer chiral information. The first methodology was based on the stereoselective transfer of ligands to α,β- unsaturated ketones mediated by organocuprates in a Michael addition reaction using (SR)- methyl-p-tolyl-sulfoxi

2. 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
