An Organotin Oxo-Carboxylate Cluster Functionalized by Triethoxysilyl Groups

摘要

The 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(0)NH(CH2)3Si(OEt)3]}6(2).Both compounds were characterized by multinuclear NMR(~(119)Sn,~1H,~(13)C,~(29)Si).
