di- and tri-alkyl-substituted allenes were potentiostatically oxidized in methanol at graphite and Pt anodes. At the former electrode, α-methoxylated ketones (due to 4F/mole electricity consumption) and esters (6F/mole) were the major products. At a Pt anode, intermediate products such as vinyl-ether derivatives (2F/mole) were characterised too. Unlike the anodic oxidation of alkenes and alkynes previously
在甲醇和石墨阳极上,单,二和三烷基取代的烯基在甲醇中被恒电位氧化。在前一个电极上,主要产品是α-甲氧基化的酮(由于消耗4F /摩尔)和酯(6F /摩尔)。在铂阳极上,也表征了中间产物,如乙烯基醚衍生物(2F /摩尔)。与先前文献中所记载的烯烃和炔烃的阳极氧化不同,二聚化不是艾伦烯氧化的典型过程,因为已观察到所有产物均仅观察到单一的二聚体。讨论了大多数产品形成的机理。
