The reaction between 2-halogeno-5-nitro-thiazoles and amines has been studied. Especially the sterically hindered strongly basic secondary aliphatic amines tend to cause opening of the thiazole ring system, resulting in the formation of the heretofore unknown (1-nitro-2-amino-vinyl)-thiocyanates. The ring opening is favored by a highly polar solvent, such as dimethyl sulfoxide. A simple reaction mechanism
已经研究了2-卤代5-硝基-噻唑与胺之间的反应。特别是在空间上受阻的强碱性仲脂族胺趋于引起噻唑环系统的打开,导致形成迄今未知的(1-硝基-2-氨基-乙烯基)-硫氰酸酯。高极性溶剂如二甲基亚砜有利于开环。提出了一种简单的反应机理,并讨论了这些新化合物的一些性质。
