In the presence of strong Lewis acids such as aluminum chloride or boron trichloride, formyl-aalen [tris(diformylamino)methane] (3) acts as a formylating reagent for aromatic alkane compounds and aromatic ethers. The orthoamide 3 delivers three formyl groups for the formylation process. Thus toluene, cumene, tert-butylbenzene, hexylbenzene, ο-xylene, ρ-cymene, biphenyl, anisole, diphenylether and 1
在强路易斯酸(如氯化铝或三氯化硼)存在下,甲酰丙二烯 [三(二甲酰氨基)甲烷] (3) 作为芳烃化合物和芳醚的甲酰化试剂。orthoamide 3 为甲酰化过程提供三个甲酰基。因此,甲苯、枯烯、叔丁基苯、己基苯、邻二甲苯、对异丙基苯、联苯、苯甲醚、二苯醚和 1,3-二甲氧基苯可以在 1,2-二氯乙烷中甲酰化。在这些反应中,3 和氯化铝的使用摩尔比应为 1:6 至 1:9。
