Abstract
The antimony aryloxide compound [κ4 -N (CH2 ArBu2t O)3] Sb may be readily obtained via the reaction of Sb(OEt)3 with tris(3,5-di-t-butyl-2-hydroxybenzyl)amine, N (CH2 ArBu2t OH)3.[κ4 -N (CH2 ArBu2t O)3] Sb forms the adduct [κ4 -N (CH2 ArBu2t O)3] Sb (OSMe2) upon treatment with Me2SO, and comparison of the molecular structure of [κ4 -N (CH2 ArBu2t O)3] Sb (OSMe2) with that of [κ4-N(o-C6H4O)3]Sb(OSMe2) demonstrates that the Sb-OSMe2 bond length in the former complex is significantly longer than that in the latter. This observation indicates that the [κ4 -N (CH2 ArBu2t O)3] ligand engenders a less Lewis acidic antimony center than does [κ4 -N (o s(-) C6 H4 O)3]. [κ4 -N (CH2 ArBu2t O)3] Sb exhibits diverse reactivity. For example, treatment of [κ4 -N (CH2 ArBu2t O)3] Sb with AcOH cleaves one of the Sb-O bonds to give [κ3 -N (CH2 ArBu2t O)2 (CH2 ArBu2t OH)] Sb (κ1 - O2 CMe), Br2 undergoes oxidative addition to give N (CH2 ArBu2t O)3] SbBr2, while Me3NO · 2H2O yields the oxo and hydroxo complexes {[κ4 -N (CH2 ArBu2t O)3] Sb (μ -O)}2, [κ4 -N (CH2 ArBu2t O)3] Sb (OH)2, and {[κ4 -N (CH2 ArBu2t O)3] SbV O}4 {Sb4III O6}.
