Irradiation of solutions of β-hydroxycobaloximes e.g. (2), (5), (9) and (13) derived from epoxy olefins [e.g. (1), (8) and (12)] and cobalt(I) dimethylglyoxime, using a sunlamp at room temperature, leads to facile cyclisation producing cycloalkanols e.g. (4), (6), (10) and (14). By contrast, only the products viz (3), (7) and (11) of dehydrocobaltation are produced when the same β-hydroxycobaloximes
使用环氧乙烷辐射源自环氧烯烃[例如(1),(8)和(12)]和钴(I)二甲基乙二肟的β-羟基钴肟的溶液,例如(2),(5),(9)和(13)。在室温下晒日光灯会导致容易的环化反应,生成环烷醇,例如(4),(6),(10)和(14)。相比之下,只有产品即当相同的β-hydroxycobaloximes被dehydrocobaltation的(3),(7)和(11)中产生加热在苯回流下进行。
