3-disubstituted thioureas using KICl2 in the presence of amines. The reactions were successfully carried out at room temperature, in short reaction time, affording cyclic/acyclic guanidines (hydrochloride salts) in high chemical yields.
通过在胺存在下使用KICl 2对1,3-二取代的硫脲进行脱硫反应,可以有效地制备胍盐。反应在室温下以短的反应时间成功地进行,以高化学收率得到环状/无环胍(盐酸盐)。
