The Lewis acid mediated Nicholas reaction of potassium alkynyltrifluoroborates and propargyl acetate-hexacarbonyldicobalt complexes affords 1,4-diyne dicobalt hexacarbonyl complexes in good yields. The analogous Nicholas reactions of potassium alkenyltrifluoro­borates give 1,3-enyne dicobalt hexacarbonyl complexes in most cases, although the initial site of reaction can vary. Potassium vinyltrifluoroborate itself affords alkynylcyclopropane complexes.

炔基-和烯基三氟硼酸盐的尼古拉斯反应

路易斯酸介导的炔基三氟硼酸钾和乙酸炔丙酯-六羰基二钴络合物的尼古拉斯反应以良好的产率提供了 1,4-二炔六羰基二钴络合物。在大多数情况下,烯基三氟硼酸钾的类似尼古拉斯反应会产生 1,3-烯炔六羰基二钴配合物,尽管反应的初始位点可能会有所不同。乙烯基三氟硼酸钾本身提供炔基环丙烷配合物。
