经氧化铜(10%mol)催化,N-次磷酰基吲哚(0.033 mol/L二氯乙烷溶液)与二芳基碘三氟甲磺酸盐(1.5倍摩尔量)于80℃反应12 h,得到相应的6-位芳基吲哚,31例收率31%~95%。吲哚环上3-、4-、5-位的取代基对该反应影响不大,仅当3-位碘代时收率较低;取代的芳基为苯环和萘环时收率较高,杂环收率较低。 Reaction of N-phosphinylindole (0.033 mol / L in dichloroethane) with diaryliodonium triflate (1.5-fold molar amount) at 80 ° C catalyzed by copper oxide (10% mol) h, the corresponding 6-aryl arylindole, 31 cases of yield of 31% to 95%. Substituents at the 3-, 4- and 5-positions of the indole ring have little effect on the reaction, yielding only lower yields at the 3-position iodide, and when the substituted aryl group is a benzene ring or a naphthalene ring High, lower yield of heterocyclic ring.
