alkylbenzenes and subsequent condensation with trialkylstannyl chloride affords allyl- or benzyl-type organotin compounds that can be isolated in pure form. Treatment with soluble reagents such as methyllithium, trimethylsilylmethylpotassium and trimethylsilylmethylcaesium generates the corresponding organoalkali derivatives almost quantitatively and in high purity, suitable for kinetic or spectroscopic studies
烯烃或烷基苯的超碱金属化,然后与三烷基锡烷基氯缩合,可得到可以纯净形式分离的烯丙基或苄基型有机锡化合物。用诸如甲基锂,三甲基甲硅烷基甲基钾和三甲基甲硅烷基甲基铯的可溶性试剂处理几乎可以定量且高纯度地产生相应的有机碱衍生物,适用于动力学或光谱研究。
