Resumo

O projeto tem como tema principal o emprego de sais de organotrifluoroboratos de potássio (espécies nucleofílicas) e visa o desenvolvimento de reações tipo Suzuki-Miyaura entre estes sais e espécies insaturadas de telúrio (espécies eletrofílicas) e haletos orgânicos, catalisadas por um complexo de metal de transição, para promover a formação de ligações sp2-sp2, sp2-sp, sp-sp para a obtenção de compostos importantes do ponto de vista sintética.
