Rousseau, Lidie published the artcileRelevance of Single-Transmetalated Resting States in Iron-Mediated Cross-Couplings: Unexpected Role of ¦Ò-Donating Additives, Name: 4,4′-Dimethyldiphenyl, the publication is Inorganic Chemistry (2021), 60(11), 7991-7997, database is CAplus and MEDLINE.
Control of the transmetalation degree of organoiron(II) species is a critical parameter in numerous Fe-catalyzed cross-couplings to ensure the success of the process. In this report, we however demonstrate that the selective formation of a monotransmetalated FeII species during the catalytic regime counterintuitively does not alone ensure an efficient suppression of the nucleophile homocoupling side reaction. It is conversely shown that a fine control of the transmetalation degree of the transient FeIII intermediates obtained after the activation of alkyl electrophiles by a single-electron transfer (SET), achievable using ¦Ò-donating additives, accounts for the selectivity of the cross-coupling pathway. This report shows for the first time that both coordination spheres of FeII resting states and FeIII short-lived intermediates must be efficiently tuned during the catalytic regime to ensure high coupling selectivities.
