Abstract

Silane dendrimer with 96 allylic end groups has been synthesized in excellent yield using repetitive alkenylation-hydrosilylation cycles. Each of the two steps provided the products in almost quantitative yields. After a simple chromotograpic purification (silica gel, chloroform), pure dendrimers were obtained and their purity was checked with 1H, 13C NMR spectroscopic method and elemental analysis.

96개의 allyl기를 가진 나무가지꼴 실란 거대분자를 alkenylation 과 hydrosilylation의 반복된 과정을 경유하여 매우 높은 수율로 합성하였다. 이 두 과정을 통해서 나무가지꼴 거대분자는 크로마토그래피법을 이용한 정제법(silica hel, chloroform)에서 순수한 물질을 얻어졌음이 $/_1/H,\;/_13/CNMR$과 원소분석 등에 의해 확인되었다.
