[(NHC)Yb{N(SiMe3)2}2]-catalyzed cross-dehydrogenative coupling of silanes with amines.
Top cat: [(NHC)Yb{N(SiMe(3))(2)}(2)] adducts are efficient catalysts for catalytic cross-dehydrogenative coupling of silanes with a range of primary and secondary amines to yield silylamines in high yields under mild reaction conditions. Expand
N-Heterocyclic Carbene-Ytterbium Amide as a Recyclable Homogeneous Precatalyst for Hydrophosphination of Alkenes and Alkynes.
To the best of the knowledge, complex 1 represents the first rare-earth complex that can be recovered after catalytic reactions and found that complex 3 could catalyze the polymerization of styrene to yield atactic polystyrenes with low molecular weights. Expand
Synthesis of 2‐(N‐arylimino)pyrrolide nickel complexes and polymerization of methyl methacrylate
The synthesis, characterization and methyl methacrylate polymerization behaviors of 2-(N-arylimino)pyrrolide nickel complexes are described. The nickel complex [NN]2Ni (1, [NN] =Expand
Reactions of the heavier group 14 element alkyne analogues Ar'EEAr' (Ar' = C6H3-2,6(C6H3-2,6-Pri2)2; E = Ge, Sn) with unsaturated molecules: probing the character of the EE multiple bonds.
Overall, the experiments showed that 1 is highly reactive toward unsaturated molecules, whereas the corresponding tin congener 2 is much less reactive. Expand
Synthesis and characterization of the non-kekulé, singlet biradicaloid Ar'Ge(μ-NSiMe3)2GeAr' (ar' = 2,6-Dipp2C6H3, Dipp = 2,6-i-Pr2C6H3)
Reaction of Ar‘GeGeAr‘ (1) with an excess of Me3SiN3 gives the non-Kekule, biradicaloid Ar‘Ge(μ-NSiMe3)2GeAr‘ (3, Ar‘ = 2,6-Dipp2C6H3, Dipp = 2,6-i-Pr2C6H3) which has a planar Ge2N2Si2 array andExpand
Facile synthesis of cyclopropene analogues of aluminum and an aluminum pinacolate, and the reactivity of LAl[eta(2)-C(2)(SiMe(3))(2)] toward unsaturated molecules (L=HC[(CMe)(NAr)](2),
The variable-temperature (1)H NMR studies of 2 and ESR measurements of 3 suggest that the Al-C-C three-membered-ring systems can be best described as metallacyclopropenes. Expand
Reactivity of Ar'GeGeAr' (Ar' = C6H3-2,6-Dipp2, Dipp = C6H3-2,6-iPr2) toward alkynes: isolation of a stable digermacyclobutadiene.
The first reactions of the "digermyne" Ar'GeGeGeAr' with alkynes are reported, and the high reactivity of 1 emphasizes the fundamental differences between the GeGe and CC multiple bonds. Expand
Stable, Monomeric Imides of Aluminum and Gallium: Synthesis and Characterization of [{HC(MeCDippN)2 }MN-2,6-Trip2 C6 H3 ] (M=Al or Ga; Dipp=2,6-iPr2 C6 H3 ; Trip=2,4,6-iPr3 C6 H2 ).
A short Ga-N bond with double-bond character is displayed by the first monomeric imide of gallium, which was obtained by the reaction of [{HC(MeCDippN)2 }M:] (Dipp=2,6-iPr2 C6 H3 , M=Ga; see picture)Expand
Synthesis of HC[(CBut)(NAr)]2Al (Ar = 2,6-Pri2C6H3) and Its Reaction with Isocyanides, a Bulky Azide, and H2O
The reaction of H2C[(CBut)2(NAr)2] (Ar = 2,6-Pri2C6H3) with AlEt3 in refluxing toluene gave HC[(CBut)2(NAr)2]AlEt2 (1) in high yield. Treatment of 1 with 2 equiv of iodine in toluene yieldedExpand
