Rare-earth metal hydroxylamide complexes.
The rare-earth metal hydroxylamide compound Y[N(SiHMe2)2]2[ONBn2][THF] (1) was prepared by the silylamide elimination pathway from the reaction of N,N-dibenzylhydroxylamine, Bn2NOH (Bn = CH2C6H5), with Y[N(SiHMe2)2]3[THF]2 and was characterised by multinuclear NMR spectroscopy and elemental analysis. The compounds [Cp2Y(ONBn2)]2 (2a) [Cp2Sm(ONBn2)]2 (2b) were obtained by the reactions of MCp3 (...
متن کاملMetal Hydrides: Transition Metal Hydride Complexes
Solid-state metal hydrides provide a safe and efficient way of storing hydrogen (Schlapbach 2002). They are commercialized for use in rechargeable batteries and developed for energy conversion devices such as fuel cells (see Hydrogen Metal Systems: Electrochemical Reactions). A great majority of metal hydrides derives from intermetallic compounds and alloys (see Hydrogen Metal Systems: Hydride ...
متن کاملTetrahydropentalenyl-phosphazene constrained geometry complexes of rare-earth metal alkyls.
Reactions of Cp™HPPh2 (1, diphenyl(4,4,6,6-tetramethyl-1,4,5,6-tetrahydropentalen-2-yl)phosphane) with the organic azides AdN3 and DipN3 (Ad = 1-adamantyl; Dip = 2,6-di-iso-propylphenyl) led to the formation of two novel CpPN ligands: P-amino-cyclopentadienylidene-phosphorane (Cp™PPh2NHAd; L(Ad)H) and P-cyclopentadienyl-iminophosphorane (Cp™HPPh2NDip; L(Dip)H). Both were characterized by NMR sp...
متن کاملChiral poly-rare earth metal complexes in asymmetric catalysis
Asymmetric catalysis is a powerful component of modern synthetic organic chemistry. To further broaden the scope and utility of asymmetric catalysis, new basic concepts for the design of asymmetric catalysts are crucial. Because most chemical reactions involve bond-formation between two substrates or moieties, high enantioselectivity and catalyst activity should be realized if an asymmetric cat...
متن کاملAmido-stabilized rare-earth metal mixed methyl methylidene complexes.
Donor(thf)-induced tetramethylaluminate cleavage of Ln(AlMe(4))(2)(NSiMe(3)Ar(iPr)) as well as the reaction of (LnMe(3))(n) (Ln = Y, Ho, Lu) with HNSiMe(3)Ar(iPr) in tetrahydrofuran affords unprecedented trinuclear rare-earth metal tetramethyl methylidene complexes which act as Schrock-type nucleophilic carbenes and methyl transfer agents.
