C-acyl-N-(3-phenyl-5-pyrazolyl)hydrazonoyl chlorides 1a,b react with potassium thiocyanate and potassium selenocyanate to give 5-acyl-2,3-dihydro-2-imino-3-(3′-phenyl)pyrazol-5′-yl)-1,3,4-thiadiazoles 2a,b and 5-acetyl-2,3-dihydro;-2-imino-3-(3′-phenyl)pyrazol-5′-yl)-1,3,4-selenadiazole 10a,b. Also, 2-[mercapto-(methylthio)methylene]indan-1,3-dione 16 reacts with hydrazonoyl halides 15 and 22–25 to afford
C-酰基-N-(3-苯基-5-吡唑基)腙酰氯 1a,b 与硫氰酸钾和硒氰酸钾反应生成 5-酰基-2,3-二氢-2-亚氨基-3-(3'-苯基) )吡唑-5'-基)-1,3,4-噻二唑2a,b和5-乙酰基-2,3-二氢;-2-亚氨基-3-(3'-苯基)吡唑-5'-基) -1,3,4-硒二唑 10a,b。此外,2-[巯基-(甲硫基)亚甲基]茚满-1,3-二酮 16 与腙酰卤 15 和 22-25 反应生成 2,3-二氢-1,3,4-噻二唑 19 和 26-29,分别。在光谱数据、化学转化和替代合成方法的基础上阐明了新合成化合物的结构。© 2001 John Wiley & Sons, Inc. 杂原子化学 12:468–474, 2001
