Síntese de pequenas bibliotecas empregando organotrifluoroboratos de potássio em reações de Suzuki-Miyaura

Resumo

O projeto tem como tema principal, porém não exclusivo, o emprego de sais de organotrifluoroboratos de potássio (espécies nucleofílicas) na formação de ligações carbono-carbono (ligações sp2-sp2, sp2-sp, sp-sp) com haletos orgânicos e espécies insaturadas de telúrio (espécies eletrofílicas), esta última como alternativa aos haletos orgânicos tradicionais, catalisadas por um complexo de metal de transição. Visa o desenvolvimento de reações tipo Suzuki-Miyaura ou outras que sejam viáveis ao uso desta classe de reagentes e a obtenção de pequenas bibliotecas de compostos para disponibilização para testes biológicos.
