Neste trabalho sintetizou-se álcoois de moléculas policíclicas tensas e seus respectivos fosfinitos, cujo esqueleto básico é constituído de norbornanos e compostos endo-endo e exo-endo tetraciclododecanos, com o objetivo de usá-los na preparação de catalisadores catiônicos de Ródio. Utilizou-se o ácido α-acetamidocinâmico, uma olefina pró-quiral, para testar o potencial catalítico dos compostos preparados.In this work polycyclic alcohols of strained molecules, whose basic structures were made of norbomanes, endo-endo and endo-exo tetracyclic dodecanes compounds, were prepared. Their respective phosphinites were synthesized to be used as ligands in Rhodium cationic catalysts' systems. α acetoamidocinnamic acid, a pro-chiral olefin, was used in order to test the catalytic potential of these prepared compounds.
