Abstract
Reactions of [H2N(CH2)3]8Si8O12 or its octahydrochloride salt with a variety of electrophiles, including anhydrides, lactones, acid chlorides, α,β-unsaturated esters and isocyanates, afforded functionalized R8Si8O12 frameworks in good to excellent yields. Practical methods for the synthesis of [HO(CH2)3]8Si8O12, [OCN(CH2)3]8Si8O12 and [(Ph2PCH2)2N(CH2)3]8Si8O12 are also reported.Keywords
