Preparation and reactivity of chiral and achiral NCN pincer Fe complexes containing bis(oxazolinyl)phenyl (abbreviated as phebox) ligands with SnMe 3 , SiMe 3 , Me, and Ph ligands were investigated. Irradiation of (phebox)SnMe 3 (2) with 1 equiv of Fe(CO) 5 led to oxidative addition to give NCN pincer stannyl complex (phebox)Fe(CO) 2 (SnMe 3 ) (3). Similarly, oxidative addition of (phebox)SiMe 3 (4) with Fe(CO) 5 resulted in the formation of silyl complex (phebox)Fe(CO) 2 SiMe 3 (5). Me and Ph complexes (phebox)Fe(CO) 2 R (7, R = Me; 8, R = Ph) were synthesized by transmetalation of the bromide complex (phebox)Fe(CO) 2 Br (1) with ZnMe 2 and ZnPh 2 , respectively. These phebox Fe complexes served as catalysts for hydrosilylation of a ketone and C−H silylation of N-methylindole.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
