Abstract
Four monodentate benzoferrocenyl phosphines were studied as supporting ligands in palladium-catalyzed Suzuki–Miyaura coupling of aryl chlorides with arylboronic acids. Of these ligands, the more electron-rich and steric demanding benzoferrocenyl dicyclohexyl phosphine was found highly effective for the reaction followed by the benzoferrocenyl diisopropyl phosphine. The corresponding diethyl and diphenyl phosphines are much ...
