Using Functionalized Silyl Ligands To Suppress Solvent Coordination to Silyl Lanthanide(II) Complexes
The reaction of the potassium 1,3-trisilanediide Me2Si[Si(Me3Si)2K]2 with SmI2 and YbI2 was found to give the respective disilylated complexes Me2Si[Si(Me3Si)2]2Sm·2THF and Me2Si[Si(Me3Si)2]2Yb·2THF. Desolvation of coordinated solvent molecules in these complexes made their handling difficult. However, using a number of functionalized silanide ligands, complexes with a diminished number or even...
متن کاملFacile access to silyl-functionalized N-heterocyclic olefins with HSiCl3.
N-heterocyclic olefins (NHOs), IPrCH2 (1) and SIPrCH2 (2) (IPrCH2 = {N(2,6-iPr2C6H3)CH}2CCH2 and SIPrCH2 = {N(2,6-iPr2C6H3)CH2}2CCH2), react with HSiCl3 and afford IPrCH(SiHCl2) (3) and SIPrCH(SiHCl2) (4), respectively. Compounds 3 and 4 have been isolated in almost quantitative yield. Interestingly, treatment of the silylene IPr·SiCl2 with 1 also affords 3, where silylene insertion into a C–H ...
متن کاملSynthesis, characterisation, and dehydrocoupling ability of zirconium complexes bearing hindered bis(amido)silyl ligands.
Herein we detail the synthesis and characterisation of a series of zirconium compounds featuring the bis(amido)silyl ligand [(i)Pr2Si(NDipp)2](2-) (Dipp = 2,6-diisopropylphenyl). The functionalisation of bis(amido)silyl zirconium halide complexes with a variety of nucleophiles, such as LiNMe2, LiBH4 and MeLi, was explored and the resulting products showed a propensity to form anionic zirconate ...
متن کاملCatalytic enantioselective addition of Grignard reagents to aromatic silyl ketimines
α-Chiral amines are of significant importance in medicinal chemistry, asymmetric synthesis and material science, but methods for their efficient synthesis are scarce. In particular, the synthesis of α-chiral amines with the challenging tetrasubstituted carbon stereocentre is a long-standing problem and catalytic asymmetric additions of organometallic reagents to ketimines that would give direct...
متن کاملMetal-to-Metal Silyl Migration and Silicon-Carbon Bond Cleavage/Re-formation Processes in the Methylene/Silyl
Ruthenium methylene/silyl complexes of stoichiometry Cp*2Ru2(μ-CH2)(SiR3)(μ-Cl), where SiR3 ) SiMe3 (1), SiEt3 (2), SiMe2Et (3), and SiMe2Ph (4), are produced when [Cp*RuCl]4 is treated with the appropriate dialkylmagnesium reagent, Mg(CH2SiR3)2. Each complex undergoes two fluxional processes as observed by variable-temperature 1H NMR spectroscopy. The low-temperature exchange process is migrat...
