含氟取代基的β-二亚胺化合物的合成

Synthesis of β-ketiminates with fluorine substituents

以乙酰丙酮和氟代苯胺为原料,等摩尔量的对甲苯磺酸为催化剂,高收率地制备了6种芳环上含氟取代基的N,N-二芳基-2,4-戊二亚胺化合物(β-二亚胺),其中5种未见文献报道。产物通过1HNMR、IR和元素分析进行表征。

Six β-ketiminates with fluro substituents on aryl ring were synthesized in good yields by the condensation of acetylacetone with fluro-substituted anilines and equivalent p-TsOH as catalyst.Five of these products have not been reported previously.All the title compounds reported were characterized by 1HNMR,IR and elemental analysis.
