Journal ArticleDOI
Lanthanide complexes coordinated by N-substituted (R)-1,1'-binaphthyl-2,2'-diamido ligands in the catalysis of enantioselective intramolecular hydroamination.
TL;DR: Ytterbium complexes proved to be both the most active and the most enantioselective, and the use of the complex, bearing isopropyl radicals on the nitrogen atoms, allowed the formation of the corresponding spiropyrrolidine in high yield with up to 70 % ee.
Journal ArticleDOI
Ruthenium Complexes Containing Two Ru−(η2-Si−H) Bonds: Synthesis, Spectroscopic Properties, Structural Data, Theoretical Calculations, and Reactivity Studies
Fabien Delpech,Sylviane Sabo-Etienne,Jean-Claude Daran,Bruno Chaudret,Khansaa Hussein,Colin J. Marsden,Jean-Claude Barthelat +6 more
TL;DR: The bis-dihydrogen complex RuH2(H2)2(PCy3)2 (1) reacts with the disilanes (R2SiH)2X to produce the dihydride complexes as discussed by the authors.
Journal ArticleDOI
Lanthanide complexes derived from (R)-1,1′-binaphthyl-2,2′-bis(neopentylamine)–{Li(THF)4}{Ln[(R)-C20H12N2(C10H22)]2}(Ln = Sm, Yb)– novel catalysts for enantioselective intramolecular hydroamination
TL;DR: The complexes (Li(THF)4)(Ln[(R)-C20H12N2(C10H22)]2) (Ln = Sm, Yb) have been synthesized, fully characterized and found to be efficient and enantioselective catalysts for intramolecular hydroamination of 1-(aminomethyl)-1-allylcyclohexane.
Journal ArticleDOI
A Mechanistic Investigation of Oxidative Addition of Methyl Iodide to [Tp*Rh(CO)(L)]
Valérie Chauby,Jean-Claude Daran,Carole Serra-Le Berre,Francois Malbosc,Philippe Kalck,Oscar Delgado Gonzalez,Claire E. Haslam,Anthony Haynes +7 more
TL;DR: The results strengthen the evidence in favor of an S(N)2 mechanism for oxidative addition of MeI to square planar d(8) transition metal complexes.
Journal ArticleDOI
One pot synthesis of nitrogen-containing polycyclic δ-lactones by double nucleophilic addition of bis(trimethylsilyl)ketene acetals to pyridines
TL;DR: Pyridine and bis(TMS)ketene acetals react successively with methylchloroformate and iodine to give, via functionalized dihydropyridines, bicyclic nitrogen-containing lactones which have been characterized by X-ray crystallography.
