Reaction of trimethylaluminium with main group hydroxides: A non-hydrolysis route to methylalumoxane
Obrey,Barron
, p. 2456 - 2458 (2007/10/03)
Reaction of AlMe3 with [(tBu)2Ga(μ-OH)]3 or Ph3EOH (E = Sn, Pb) yields catalytically active MAO, [MeAlO]n, along with (tBu)2GaMe and Ph3EMe, respectively, in contrast, the reaction with Ph3EOH (E = C, Si, Ge) yields [Me2Al(μ-OEPh3)]2; the formation of MAO is proposed to occur via hydroxide exchange and the formation of unstable [Me2Al(μ-OH)]n; the propensity towards alkane elimination versus hydroxide exchange is controlled by the relative Bronsted acidity of the main group hydroxide.
New Reagents, XXX: Synthesis and Stability of Bis(triphenylplumbyl)methyllithium and Reactions with Alkyl Halides, Carbonyl Compounds, and Oxiranes
Kauffmann, Thomas,Rensing, Alfons
, p. 380 - 390 (2007/10/02)
Bis(triphenylplumbyl)methyllithium (2) is easily accessible by plumbyl-Li or Br-Li exchange from tris(triphenylplumbyl)methane (1b) and bromobis(triphenylplumbyl)methane (3), respectively.Due to its stability and high nucleophilicity 2 is a good reagent for the synthesis of bis(plumbyl)alkanes, -β-hydroxyalkanes, and -γ-hydroxyalkanes.
