potassium cyclopentadienide to give, respectively, ClSi[(CH2)3SiMe2Bz]3 (8) and (C5H5)Si[(CH2)3SiMe2Bz]3 (10). This strategy can be applied to the post-growth incorporation of nucleophiles to the focal point of carbosilane dendritic wedges. In this way, cyclopentadiene-functionalized dendritic wedges of second and third generation C5H5-Gn-[(CH2)3SiMe2Bz]x (n = 2, x = 9, 11; n = 3, x = 27, 12) have been obtained
PhSi[(
CH2)3SiMe2Bz]3 (5) 的 Si-Ph 键用
三氟甲磺酸裂解得到 TfOSi[( )3SiMe2Bz]3,后者又与三乙基
氯化铵或
环戊二烯化
钾反应,分别得到: ClSi[( )3SiMe2Bz]3 (8) 和 (
C5H5)Si[( )3SiMe2Bz]3 (10)。这种策略可以应用于亲核试剂在碳
硅烷枝晶楔形焦点的生长后掺入。通过这种方式,获得了第二代和第三代 -Gn-[( )3SiMe2Bz]x (n = 2, x = 9, 11; n = 3, x = 27, 12) 的
环戊二烯功能化树枝状楔块来自 Ph-Gn-[( )3SiMe2Bz]x (6, 7)。茂
金属 [(BzMe2Si )3SiC5H4}2MCl2] (M = Ti, 14; Zr, 15) 也已从 10 和它们在
