of substituted benzyldimethylsilanes (I) and phenyltetramethyldisilanes (II) are reported. 29SiH and 13CH coupling constants are shown to be correlated by Hammett σ constants. The data are discussed in terms of mechanisms of transmission of substituent effects across C—Si and Si—Si bonds. A good Hammett correlation is also found of J(13CH) for the benzylic protons of a series of substituted toluenes
报告了一系列取代的苄基二甲基硅烷(I)和苯基四甲基二硅烷(II)的NMR光谱数据。29 SiH和13个CH耦合常数被示出为通过哈米特σ常数相关。根据取代基效应跨C-Si和Si-Si键的传递机理来讨论数据。一个良好的相关性哈梅特还发现的Ĵ(13对于一系列取代的甲苯的苄型质子CH)。
