We observed distinct chemoselectivities for the gold-catalyzed transformation of cis-1-oxiranyl-1-alkynylcyclopropanes 1 into various halogenated products in the presence of suitable Au(III) catalysts and N-halosuccinimide (halo = chloro, bromo and iodo).
我们观察到,在合适的 Au(III)催化剂和 N-卤代琥珀酰亚胺(卤 = 氯、溴和碘)存在下,顺式-1-氧杂环戊烷-1-炔基环丙烷 1 的金催化转化为各种卤代产物具有明显的化学选择性。
