friendly electrolytic system using recyclable solid-supported bases for in situ generation of a supporting electrolyte from methanol as a solvent. It was found that solid-supported bases are electrochemically inactive at an electrode surface. It was also found that solid-supported bases dissociate methanol into methoxide anions and protons. Therefore, in the presence of solid-supported bases, it was
我们已经成功开发了一种新型的环保电解系统,该系统使用可回收的固体负载型碱,用于以甲醇为溶剂原位生成支持电解质。已发现固体负载的碱在电极表面上是电化学惰性的。还发现固体负载的碱将甲醇分解成甲醇根阴离子和质子。因此,在存在固体负载的碱的情况下,已经明确了甲醇既是溶剂又是原位生成的支持电解质。用固体负载的碱对各种化合物进行阳极甲氧基化,以提供良好至极佳收率的相应甲氧基化产物,只有少数例外。甲氧基化产物和固体负载的碱仅通过过滤即可轻松分离,只需浓缩滤液就可以很容易地分离出所需的纯甲氧基化产物。分离并回收的固体负载的碱可循环使用几次。
