p-Aminobenzyl-tris(hydroxymethyl)methane has been prepared in 5 steps from diethylmalonate and p-nitrobenzyl bromide, with an overall yield of 23%. This compound could be grafted on silica previously derivatized with 3-isocynatopropyltriethoxysilane.
对氨基苄基-三(羟甲基)甲烷是由二乙基丙二酸二酯和对硝基苄基溴经 5 个步骤制备而成的,总收率为 23%。这种化合物可以接枝到之前用 3-异炔丙基三乙氧基硅烷衍生过的二氧化硅上。
