Reaccions de cicloaddició [2+2+2] catalitzades per Rh(I)

Abstract

The development of new chemical processes and efficient catalysts for the formation of carbon-carbon bonds is an important topic in organic chemistry. In particular, the [2+2+2] cycloaddition reaction involving different insaturations mainly alkynes, alkenes and nitriles is a highly efficient synthetic tool that allows polysubstituted benzenic, cyclohexadienic and pyridinic compounds to be obtained in one reaction step and in an atom economy process, resulting in the simultaneous formation of three new bonds in the formed ring. In recent years, research to produce new catalysts that can work effectively in mild reaction conditions has attracted great interest, as has the use of these processes in the synthesis of products of potential biological interest. This doctoral thesis is based on the methodological study of the rhodium(I)-catalyzed [2+2+2] cycloaddition reaction.
