Another ACS Catalysis for this 2024, also with Dr. Lázaro-Milla as first author. Take a look, it's on-line and OA!
07/20/2024We are so pleased to announce our second research article at ACS catal. for 2024, entitled "Cobalt-Catalyzed (3 + 2) Cycloaddition of Cyclopropene-Tethered Alkynes: Versatile Access to Bicyclic Cyclopentadienyl Systems and Their CpM Complexes" and authored by C. Lázaro-Milla, E. Da Concepción, I. Fernández, J. L. Mascareñas and F. López, has been accepted and it's already on-line (gold Open Access).
Abstract: Low-valent cobalt complexes can promote intramolecular (3 + 2) cycloadditions of alkyne-tethered cyclopropenes to provide bicyclic systems containing highly substituted cyclopentadienyl moieties with electronically diverse functional groups. The adducts can be easily transformed into new types of CpRh(III) and CpIr(III) complexes, which show catalytic activity in several relevant transformations. Preliminary computational (DFT) and experimental studies provide relevant information on the mechanistic peculiarities of the cobalt-catalyzed process and allow us to rationalize its advantages over the homologous rhodium-promoted reaction.
