“…The coordination chemistry of antimony alkoxide and aryloxide compounds is, however, complex, as illustrated by the structural variations that are observed for [Sb(OMe) 3 ] n [5], [Sb(OPr i ) 3 ] 2 [6], [Sb(OSiMe 3 ) 3 ] 2 [7,8], Sb(OC 6 H 3 -2,6-Me 2 ) 3 [9], and [Sb 2 (OCH 2 CH 2 O) 3 ] n [10]. As part of an effort to investigate the reactivity of well-defined antimony aryloxide compounds, we recently described the first application of the tris(phenol)amine N(o-C 6 H 4 OH) 3 to antimony chemistry [11]. In this paper, we describe an extension of these investigations by employing tris(3,5-dit-butyl-2-hydroxybenzyl)amine, NðCH 2 Ar Bu t 2 OHÞ 3 [12], with the notion that the methylene spacer between the nitrogen and the phenol group would modulate the electronic and geometric properties of the antimony center, such as its Lewis acidity.…”
