Fj. Feher et al., PRACTICAL METHODS FOR SYNTHESIZING 4 INCOMPLETELY CONDENSED SILSESQUIOXANES FROM A SINGLE R8SI8O12 FRAMEWORK, Chemical communications, (12), 1998, pp. 1279-1280
The reaction of (c-C6H11)(8)Si8O12 1 with triflic acid (TfOH) can prod
uce two different ditriflates with the formula (c-C6H11)(8)Si8O11(OTf)
(2), which can be hydrolyzed selectively to four different incompletel
y condensed silsesquioxane frameworks with the formula (c-C6H11)(8)Si8
O11(OH)(2) (2, 4, 7 and 8).
