含二茂铁硅杂噁唑烷的合成

Sythesis of FerroceneContaining SilaOxazolidines

由α－卤代苯基二茂铁甲醇与二乙醇胺反应，合成了一系列卤代苯基二茂铁基双（β－羟乙基）甲胺，后者与二乙氧基硅烷发生酯交换反应，合成了一类新的含二茂铁硅杂口恶唑烷．由于氮原子孤对电子与硅原子空ｄ－轨道的作用，使这类化合物的红外光谱和核磁共振氢谱均表现出特殊的性质．

A new type of silocanes were synthesized by the following reactions:were x=H;o,m,pCl;pBr;pI;R=Me,OEt;These compounds were characterized by IR spectra,1HNMR spectra as well as elemental analysis.The results indicate that the transannular N→Si dative bond in this class of silocanes is very weak.We can′t find N→Si bond stretching vibrations in IR spectra.
