The synthesis and spectroscopic characteristics of 28 para-substituted aryltrimethyl-silicon, -germanium, and -tin compounds are described. The infrared spectra show characteristic bands at 1245–1165 (methyl bend), 840–765 (methyl rock), and 1105–1020 (in-plane aromatic H bend) cm−1; the frequency of the last band was found to depend on the sum of the aromatic substituent masses, the presence or absence
描述了28种对位取代的芳基三甲基硅,-锗和-锡化合物的合成和光谱特征。红外光谱显示了在1245-1165(甲基弯曲),840-765(甲基岩石)和1105-1020(面内芳族H弯曲)cm -1处的特征谱带;发现最后一个带的频率取决于芳族取代基质量的总和,在取代基中金属成分的存在或不存在影响很小。质谱碎裂模式是根据金属原子上正电荷的位置来解释的,其后的键裂解行为符合碳化合物质谱的规则。
