The reactions of 4-isothiocyanato-2,2,6,6-tetramethylpiperidine-1-oxyl 2 and 4-isocyanato-2,2,6,6-tetramethylpiperidine-1-oxyl 3 with selected amines and lower alcohols give the corresponding novel thioureas 4, ureas 5, thiocarbamates 6, and carbamates 7, all bearing the nitroxyl moiety. The characteristic features of EI mass spectra of (thio)ureas 4 and 5 are described. Some of the synthesized thioureas
4-isothiocyanato-2,2,6,6-tetramethylpiperidine-1-oxyl 2 和 4-isocyanato-2,2,6,6-tetramethylpiperidine-1-oxyl 3 与选定的胺和低级醇的反应得到相应的新型硫脲 4、脲 5、硫代氨基甲酸酯 6 和氨基甲酸酯 7,均带有硝酰基部分。描述了(硫)脲 4 和 5 的 EI 质谱的特征。合成的硫脲 4、脲 5、硫代氨基甲酸酯 6 和氨基甲酸酯 7 中的一些对病原真菌具有中度或弱活性。© 2006 Wiley Periodicals, Inc. 杂原子化学 17:393–401, 2006; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20228
