Abstract

ABSTRACTThe organotin oxo-carboxylate cluster {BuSnO(O2CC6H4-4-NH2)}6 (1), which exhibits a hexagonal prismatic oxo-core, was synthesized from BuSnO (OH) and p-aminobenzoic acid. Its peripheral functionalization with triethoxysilyl moieties was achieved through the reaction with 3-isocyanatopropyltriethoxysilane (ICPTES) which preserves the oxo-carboxylate framework and yields {BuSnO[O2CC6H4-4-NHC (O)NH (CH2)3Si (OEt)3]}6 (2). Both compounds were characterized by multinuclear NMR (119Sn, 1H, 13C, 29Si).
