The reaction of the sterically hindered terphenol Ar∗OH(Ar∗=C6H3-2,6(C6H2-2,4,6-Pr3i)2) with trimethylaluminum or trimethylgallium in ether led to the isolation of the corresponding ether-coordinated monophenoxide species Ar*OM(CH3)2(Et2O) (M = Al (1) or Ga (2)). The reaction of the lithium salt of the related bulky terphenol Ar′OH(Ar′=C6H3-2,6(C6H3-2,6-Pr3i)2) with the divalent species MCl2 (M = Ge, Sn) afforded the novel germanium (II) and tin (II) mono- and bisphenoxides [{Ar′OGeCl}(dioxane)] · toluene (3 · toluene), Ge(OAr′)2 (4) and Sn(OAr′)2 (5). The compounds were characterized by 1H, 13C and 119Sn NMR (5) spectroscopy, and by IR spectroscopy and X-ray crystallography.
Sterically encumbering terphenoxide ligands have been used to isolate aluminum and gallium alkyl derivatives as well as low coordinate germanium and tin divalent compounds.Figure optionsDownload as PowerPoint slide
