Reactions of Hydrazonoyl Halides 33 1 : Synthesis of Some New 2,3-Dihydro-1,3,4-thiadiazoles Containing Pyrazol-3-yl, Indolin-2-one-2-yl and Indan-1,3-dione-2-yl Moieties

Some new 2,3-dihydro-1,3,4-thiadiazoles containing pyrazol-3-yl, indolin-2-one-2-yl and indan-1,3-dione-2-yl moieties in a good yields obtained from the reaction of hydrazonoyl halides with thiocarbamate and carbodithioate in ethanolic triethylamine respectively. In contrast, pyrazolylthiourea reacts with hydrazonoyl halides under the same condition afford corresponding hydrazonoyl sulfide derivatives
一些新的含有 pyrazol-3-yl、indolin-2-one-2-yl 和 indan-1,3-dione-2-yl 部分的新 2,3-dihydro-1,3,4-thiadiazoles 从腙酰卤分别与硫代氨基甲酸酯和二硫代碳酸酯在乙醇三乙胺中的反应。相比之下,吡唑基硫脲在相同条件下与腙酰卤反应,得到相应的腙酰硫化物衍生物。
