摘要:
An incompletely condensed silsesquioxane containing trisilanol (c-C5H9)(7)Si7O9(OH)(3) reacts with [PdI2(bpy)] (bpy 2,2'-bipyridine) in the presence of Ag2O to produce a palladium complex with an O,O-chelating silsesquioxanate ligand, [Pd{O11Si7(c-C5H9)(7)(OH)}(bpy)] (1). The reaction of Ph2SiClH with 1 in 2: 1 ratio causes disilylations of the silsesquioxanate ligand, forming [PdCl2(bpy)]. Addition of p-cresol to a solution of 1 yields the trisilanol and [Pd(OC6H4CH3-p)(2)(bpy)]. (C) 2010 Elsevier B.V. All rights reserved.
