In the presence of hypervalent iodine reagents (PIFA), Direct coupling reaction of N-acetyl-indole with aromatic compounds provided C-3 arylated indoles in high regioselectivity.
我们使用高价有机碘试剂（PIFA）做氧化剂，实现了N-乙酰基吲哚与芳香化合物的直接偶联反应，得到了吲哚3号位高选择性的偶联产物。
The result shows: the resistivity, anti-corrosion and chemical resistance of the film from arylated alkyl amine curing agent were better than that of conventional polyamide curing agent.
指出浅色环氧防静电涂料选用芳脂胺类型的固化剂，所得漆膜的电阻率、防腐蚀性和耐化学品性均优于传统的聚酰胺固化剂。
