Copper nanoparticles (CuNPs) supported on TiO2 have shown to effectively catalyze thesynthesis of Z-alkenyl sulfides from activated alkynes and thiol derivatives, through an anti-Markovnikov process. Activated alkynes bearing an adjacent electron-withdrawing group gave good toexcellent products conversions, while the unactivated alkynes did not react. In order to give an explanation to the reactivity observed from the experimental results and to know the most simple andrepresentative structure of the catalyst, density functional theory (DFT) computational studies havebeen applied.
