New approaches to high-activity transition-metal catalysts for carbon–carbon bond forming reactions. Rhenium-containing phosphorus donor ligands for palladium-catalyzed Suzuki cross-couplings
Abstract
The rhenium complexes (η5-C5H5)Re(NO)(PPh3)((CH2)nPR2:) (n/R = 0/Ph, 0/t-Bu, 0/Me, 1/Ph, 1/t-Bu), which contain electron-rich and sterically congested phosphido moieties, give active
