通过两种取代的乙酰基二茂铁与三甲基氰硅烷的加成反应, 得到两种取代二茂铁基三甲基硅烷基氰醇醚的晶体: 1-(1-氰基-1-三甲基硅烷氧基乙烷基)二茂铁(1), 1,1'-二(1-氰基-1-三甲基硅烷氧基乙烷基)二茂铁(2), 用X射线单晶衍射、元素分析、红外光谱和核磁共振氢谱对分子结构进行了表征. 测试结果表明: 晶体1属正交晶系, Pbca空间群, a＝1.1995 nm, b＝1.2441 nm, c＝2.2183 nm, Z＝8, R1＝0.0456, wR2＝0.0880; 晶体2属正交晶系, Pna2(1)空间群, a＝2.0715 nm, b＝0.6440 nm, c＝1.8411 nm, Z＝4, R1＝0.0485, wR2＝0.0866. 晶体结构表明, 分子中都存在超共轭效应.

Two ferrocenyl and trimethylsilyl substituted cyanohydrin ethers have been prepared by the addition of trimethysilyl cyanide to two acetyl-substituted ferrocenes: 1-(1-cyano-1-trimethylsilyloxyethyl)- ferrocene (1) and 1,1'-bis(1-cyano-1-trimethylsilyloxyethyl)ferrocene (2). The structures of these two compounds were characterized by elemental analysis, IR, 1H NMR and X-ray crystallography. Crystal data: compound 1, orthorhombic Pbca, a＝1.1995 nm, b＝1.2441 nm, c＝2.2183 nm, Z＝8, R1＝0.0456, wR2＝0.0880; compound 2, orthorhombic Pna2(1), a＝2.0715 nm, b＝0.6440 nm, c＝1.8411 nm, Z＝4, R1＝0.0485, wR2＝0.0866. Crystal structures showed that there was super conjugation in both compounds.
