Resum

En aquest treball s’ha estudiat la formació de complexos de tipus bis(trifluorometil)cuprat a través d’una reacció de transmetal·lació utilitzant complexos de plata anàlegs i diferents fonts de coure(I). S’ha desenvolupat la síntesi in situ d’aquests complexos de manera ràpida i selectiva a partir de (Cat)[Ag(CF3)2] i CuI en condicions de reacció suaus. Posterior- ment se n’ha avaluat la capacitat com a agents trifluorometilants en la formació d’enllaços C-CF3 utilitzant diferents substrats model, halurs d’aril que contenen enllaços Csp2–I, Csp2–Br i Csp3–Br. És important destacar que és la primera vegada que s’ha po- gut demostrar el potencial d’aquestes espècies, ja que fins ara no se n’havia estudiat la reactivitat en profunditat.
