Cyclohexyl phosphine
WebApr 13, 2024 · Here, despite the thermodynamic favorability of substituting a phosphine with an NHC 54,56, complete substitution does not occur because a fourth IMes ligand is too sterically encumbering to bind. WebBrettPhos is a dialkylbiaryl phosphine ligand developed by the Buchwald group. It promotes cross-coupling reactions more efficiently and exhibits improved reactivity compared to other catalytic systems. It can be used in: palladium-catalyzed trifluoromethylation of aryl chlorides [ 1] Buchwald-Hartwig amination [ 2]
