[reaction: see text] Alkynyl imines underwent [4 + 2] electrocyclization in the presence of 20 mol % W(CO)(5)(THF) to give 2-arylated quinolines in good yields. A deuterium labeling study suggests that the reaction proceeds via a tungsten vinylidene complex.
[反应：见正文] 在20 mol% W(CO)₅(THF)存在下，炔基亚胺发生[4 + 2]电环化反应，以良好的产率得到2-芳基喹啉。氘标记研究表明该反应通过钨亚乙烯基络合物进行。
