Abstract
The hexasilsesquioxanes (RSiO1.5)6 (1, R = 1,1,2-trimethylpropyl; 2, R = tert-butyl) were synthesized by a new method: condensation of the corresponding silanetriol, RSi(OH)3, or 1,1,3,3-tetrahydroxydisiloxane, (HO)2RSiOSiR(OH)2, using dicyclohexylcarbodiimide (DCC) as a dehydrating reagent in DMSO or DMF.
