dc.description.abstractEnglish | This thesis presents the computational-mechanistic study of the hydrophenoxylation of diphenylacetylene assisted by [Cu(NHC)] and [Au(NHC)] catalysts. In such process, the first reaction step is the generation of the nucleophile-electrophile couple: PhO-[M(NHC)] and PhCCPh-[M(NHC)]. This couple is responsible of the reaction rate, which is defined by the nucleophilic attack in the rate determining step (rds) such as 2016 Poater’s proposal. Thus, we performed the study of the metal effect in the rds exchanging copper-, silver- and gold-IPr catalysts in the pre-activated species. Also, the ligand effect in the Cu/Au catalysis was done using NHC ligands such as IMe, IMes, SIMes and IPR*. These studies allowed us to give a clear explanation in the preference for hetero-dual-metal catalysis instead of homo-dual and assessing steric hindrance effects in the rds. Furthermore, in order to improve and expand the dual catalysis field, we introduced CAAC and PSC ligands in our study. | - |
