SỬ DỤNG LÒ VI SÓNG TỔNG HỢP MỘT SỐ HYDRAZONE CÓ CHỨA DỊ VÒNG BENZO[D]THIAZOLE TỪ NITROVANILLIN

Abstract

Using microwave in synthesising four benzo[d]thiazole-containing hydrazone derivatives ND1-ND2-ND5-ND7 was prepared via condensation reaction of hydrazide and aldehyde up to >80% yield. Structures of these derivatives were elucidated by IR, NMR and MS analysis that referred to a strong agreement between spectral data and structures. The NMR data indicate that in the solutions the examined compounds exist in syn and anti conformers in the mole ratio 2:1.
Keywords: Nitrovanillin, benzo[d]thiazole, hydrazone, microwave.
