Syntheses and molecular structures of the dialkylaluminum and -gallium stannoxides [R2M(.mu.-OSnPh3)]2

Hydrolysis of organometallic and metal–amide precursors: synthesis routes to oxo-bridged heterometallic complexes, metal-oxo clusters and metal oxide nanoparticles

“…24 Alternatively, metathesis routes can be applied to build Sn−O−M connectivity due to the greater stability of Sn−alkyl bonds in comparison to Al− or Ga−alkyl bonds. 160 A…”

Reactivity of intramolecularly coordinated aluminum compounds to R3EOH (E = Sn, Si). Remarkable migration of N,C,N and O,C,O pincer ligands

“…Reactions of 1-3 with two equivalents of R 3 SnOH (R=Ph or Me) resulted in the same products (4)(5)(6)(7)(8)(9) in the mixture with the unreacted R 3 SnOH approximately in 1:1 ratio only (based on 119 Sn NMR spectroscopy). .…”

“…Obrey and Barron [3] suggested that this reaction pattern coincides with the basicity of these hydroxides. Nevertheless reaction of (Ph 3 Sn) 2 O and Me 3 Al led to dialkylaluminum stannoxides [Me 2 Al(l-OSnPh 3 )] 2 and Ph 3 SnMe [4]. The methylation of alcohol in reaction with Me 3 Al can be also achieved under certain conditions (derivatives of stable carbocations, low temperature and presence of suitable Lewis acid catalysts) [3,5].…”

β−Diketiminate Ligand Supported Group 2 Metal Hydroxide, Halide, Oxygen Bridged Heterobimetallic and Heterotrimetallic Complexes: Synthesis and X-ray Structural Studies

“…4) Å). [140] The Al(1)-O(1)-Sn(1) core is bent with an angle of 136.90(8)° which is very slightly wider than that found in [(Me 2 Al)(μ-OSnPh 3 )] 2 (131.3(2)°).…”

“…[138,139] In 1994 Oliver and coworkers reported the dimeric structure of [Me 2 Al(OSnPh 3 )] 2 formed by the reaction of Me 3 Al with [Ph 3 Sn] 2 O. [140] However, in this thesis we have described aluminum-tin oxide compounds containing Al−O−Sn(IV) and Al−O−Sn(II) moieties 1.9. Heterotrimetallic oxygen bridged system with three different metal atoms…”
