Abstract

Practical procedures are reported for the syntheses of amine and ester-substituted silsesquioxane frameworks with the formula R8Si8O12 with R = CH2CH2CH2NH2 (2), [CH2CH2CH2NH3]Cl (3) and CH2CH2CMe2CH2CO2Me (4); the use of 2 as a core for starburst dendrimers with R = CH2CH2CH2N(CH2CH2CO2Me)2 (5) and CH2CH2CH2N(CH2CH2C(O)NHCH2CH2NH2)2 (6) is also described.
