The acetylenes 1a–e undergo silyl-cupration followed by cyclisation, the acetylenes 1f–1h react with the silyl-cuprate reagent more rapidly at the alternative electrophilic site, and the acetylenes 1i, 1j and 17 give relatively low yields of cyclic products amongst others. Ring-formation is, unusually, a not particularly favourable pathway.
烷炔1a–e经历硅烷-铜化反应后进行环化,而烷炔1f–1h在另一种电亲和位点与硅烷-铜试剂的反应速度更快,烷炔1i、1j和17等反应给出的环状产物产率相对较低。环的形成在这里是不太常见的,不是特别有利的途径。
