cis,cis,cis-1,3,5,7-Tetrahydroxy-1,3,5,7-tetraisopropylcyclotetrasiloxane (1) was synthesized. The X-ray crystallography of 1 revealed that four molecules of 1 and four molecules of water compose a cluster in the lattice. Dehydration of 1 with N,N'-dicyclohexylcarbodiimide (DCC) gave octa(isopropylsilsesquioxane) in good yield.
合成了顺式、顺式、顺式-1,3,5,7-四羟基-1,3,5,7-四异丙基环四硅氧烷(1)。1 的 X 射线晶体学显示,四个 1 分子和四个水分子在晶格中组成一个簇。用 N,N'-二环己基碳二亚胺(DCC)对 1 进行脱水,得到了辛基(异丙基硅倍半氧烷),收率很高。
