Abstract: New and efficient methods for the synthesis of cyclopentyl- and cyclohexylsilsesquioxanes are described. In the case of cyclopentylsilsesquioxane, pure trisilanol (c-C5H9)(7)-Si7O9(OH)(3) was obtained selectively within 18 h in an isolated yield of 64%. The synthesis of cyclohexylsilsesquioxanes also gives high yields, but it is not selective towards a particular structural type [main products: (c-C6H11)(6)Si6O9, (c-C6H11)(6)Si6O8(OH)(2), (c-C6H11)(7)Si7O10OH and (c-C6H11)(7)Si7O9(OH)(3)]. We discuss the crucial role of acetonitrile as a reactive solvent in these syntheses. (C) Wiley-VCH Verlag GmbH Co.
