TÓM TẮT Tổng hợp và xác định cấu trúc một số hợp chất 4-(2-arylidenehydrazinyl)-7-chloroquinoline 7-Chloro-4-hydrazinylquinoline và bảy dẫn xuất dạng hydrazone của nó (trong đó có 3 hợp chất mới) đã được tổng hợp từ 4,7-dichloroquinoline. Cấu trúc của các chất tổng hợp được đã được xác nhận bởi các phổ IR, 1H-NMR, 13C-NMR và phổ khối lượng độ phân giải cao. Từ khóa: 4-(2-arylidenehydrazinyl)-7-chloroquinoline, 7-chloro-4-hydrazinylquinoline, 4,7dichloroquinoline. 1. Introduction Hydrazones containing quinoline heterocycle have been of great interest in medicinal chemistry for their role as anticancer, antibacterial, antifungal, anti-tubercular agents [1-7]. It has been evidenced from literature survey that the bioactivity of these compounds were affected by the presence or absence of chlorine substituent at the 7 th position in quinoline heterocycle as well as the properties of some substituents in molecule of these hydrazones [4,5]. Although synthesis and bioactive of some hydrazones synthesized from 4,7dichloroquinoline were reported, spectral data
