Abstract in Portuguese
Esta tese teve por principal objetivo o estudo de algumas reações envolvendo os grupos alquilselenolato e alquiltelurolato, preparados a partir dos elementos Se e Te e alquillítio comercial. A primeira parte desta tese é dedicada ao estudo da utilização de butiltelurolato e butilselenolato como ligantes não transferíveis em organocupratos, especialmente na adição conjugada a sistemas carbonílicos α,β-insaturados. Na segunda parte deste trabalho, é apresentado um estudo envolvendo a hidroteluração e hidrosselenilação de olefinas ativadas, geradas pela adição de alquilcalcogenatos em enonas, ésteres, aldeídos e nitrilas α,β insaturadas.

Abstract in English
This thesis has the main purpose of studying some on reactions involving alkylselenolate and alkyltellurolate groups obtained from elemental Se and Te and commercial alkyllithiums. The first part of this thesis deals with the study of the use of butyltellurolate and butylselenolate as non-transferible ligands in the chemistry of cuprates, in special conjugated addition to α,β-unsaturated carbonylic systems. In the second part of this work, a study involving the hydrotelluration and hydroselenilation of activated olefins prepared by addition of alkylcalcogenates in enones. esteres, aldehydes and α,β unsaturated nitriles, is presented.
