N-芳基-α-氯乙酰胺和硫氰酸钾反应可以生成不同的产物,本世纪初已分离并鉴定了三种化合物即N-芳基-α-硫氰基乙酰胺(I)、3-芳基-2-亚氨基-4-噻唑烷酮(II)和2-芳亚氨基-4-噻唑烷酮(III).(I)在加热时可以环化成(II),并重排成(III)或2-芳氨基-4-噻唑啉酮(IV),也有报导认为生成了2-芳氨基-4-羟基噻唑(V).当N-苯基上的邻对位具有不同取代基时,在某些情况下不能得到(I)形式的产物,而直接进行了环化和重排.M.Kh.Mukhitdenova等将N-芳基-α-硫氰基乙酰胺在乙醇水溶液中长期加热时得到了N-芳基-α-氨基甲酰硫代乙酰胺(VI).由于实验条件的不同,得到的产物也不相同,因此有必要对此反应作进一步的研究.
N-aryl-α-chloroacetamide reacted with potassium thiocyanate to produce different products. Three compounds were identified and identified as N-aryl-α-thiocyanoacetamide (I) Thiazolidinone (II) and 2-arylimino-4-thiazolidinone (III) can be cyclized to (II) upon heating and rearranged into (III) or 2-arylamino-4-thiazolone (IV), there are also reports that 2-arylamino-4-hydroxythiazole (V) has been reported.When the ortho position on N-phenyl has different substituents , The products in the form of (I) can not be obtained in some cases and cyclization and rearrangement are carried out directly, and M.Kh.Mukhitdenova et al. Have long-term N-aryl-α-thiocyanoacetamide in aqueous ethanol Upon heating, N-aryl-α-carbamoylthioacetamide (VI) was obtained.Due to the different experimental conditions, the obtained products are not the same, so it is necessary to further study the reaction.
