reaction. 1,2-Diazetidine derivatives bearing various N-arylsulfonyl groups were readily accessed and studied by experimental and computed Raman spectra. The ring-opening reaction of the diazetidine was explored and resulted in the identification of a selective N–N bond cleavage with thiols as nucleophiles, which stereoselectively produced a new class of N-sulfenylimine derivatives with C-aminomethyl groups
C-未取代的1,2-二氮杂环丁烷(一种很少研究的四元杂环化合物)是通过操作上简单的分子间邻位不饱和反应合成的。带有各种N-芳基磺酰基的1,2-二氮杂环丁烷衍生物易于获得,并通过实验和计算的拉曼光谱进行研究。探索了二氮杂环丁烷的开环反应,并鉴定了以硫醇作为亲核试剂选择性进行的N–N键裂解,从而立体选择性地产生了具有C-氨甲基基团的新型N-硫亚基亚胺衍生物。
