Abstract: A general method has been developed for the preparation of silsesquioxanes with potentially polymerizable p,p′-disubstituted diphenylmethyl groups attached to one vertex of the “T8” framework, including [Cy7Si8O12(CH2)4CH(C6H4OH)2] (9a), [Cy7Si8O12(CH2)l0CH-(C6H4OH)2] (9b),[Cy7Si8O12(CH2)4CH(C6H4NH2)2] (10a), [Cy7Si8O12(CH2)10CH(C6H4 NH2)2] (10b), [Cy7Si8O12(CH2)4CH(C6H4CO2H)2] (14). The reaction of [Cy7Si8O12CH2CH2CO2CH3] (2) with BrMgC6H4OCH2Ph (6a) affords an interesting disilanol derived from the hydrolytic cleavage of one Si-O-Si linkage in a completely condensed T8 framework.
