Practical methods for synthesizing four incompletely condensed silsesquioxanes from a single R₈Si₈O₁₂ framework

Abstract

The reaction of (c-C₆H₁₁)₈Si₈O₁₂ 1 with triflic acid (TfOH) can produce two different ditriflates with the formula (c-C₆H₁₁)₈Si₈O₁₁(OTf)₂, which can be hydrolyzed selectively to four different incompletely condensed silsesquioxane frameworks with the formula (c-C₆H₁₁)₈Si₈O₁₁(OH)₂ (2, 4, 7 and 8).
