摘要
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=1.1995nm,b=1.2441nm,c=2.2183nm,Z=8,R1=0.0456,wR2=0.0880;晶体2属正交晶系,Pna2(1)空间群,a=2.0715nm,b=0.6440nm,c=1.8411nm,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.
