were studied in the radical reduction of 2-bromoethyl phenyl ether in ethanol in the presence of triethylborane under aerobic conditions. The results showed that diarylsilane was the most effective among them. The radical reduction of alkyl and aryl halides with diarylsilane was applied to a reaction in aqueous media, which gave the corresponding reduction product in good yields. Thus, the present organosilanes
研究了新型水溶性有机硅烷化合物的开发及其在水介质中自由基反应的应用。通过三氯硅烷或四氯硅烷与格氏试剂反应,合成了一系列具有亲水基团的新型有机硅烷化合物,如侧链上带有醚基和羟基以承担亲水性。在有氧条件下,在三乙基硼烷存在下,在乙醇中自由基还原 2-溴乙基苯基醚中研究了这些有机硅烷化合物的反应性。结果表明,二芳基硅烷是其中最有效的。烷基和芳基卤化物与二芳基硅烷的自由基还原应用于水性介质中的反应,以良好的产率得到相应的还原产物。因此,
