regioselectivity. Cleavage requires addition of thiolate at the sulfonamide carbon, but some addition occurs at the nitro carbon resulting in simple displacement of the nitro group rather than sulfonamide cleavage. The side reaction is most prevalent with cyclic amines and steric effects play only a limited role. This lack of regioselectivity is not observed for o-nitrobenzenesulfonamides.
发现使用硫醇盐裂解对硝基苯磺酰胺的区域选择性差。裂解需要在磺酰胺碳上添加硫醇盐,但是在硝基碳上发生一些加成,导致硝基的简单置换而不是磺酰胺裂解。副反应在环胺中最为普遍,且空间效应仅发挥有限的作用。对于邻硝基苯磺酰胺没有观察到区域选择性的缺乏。
