Processes are disclosed for preparation of N-aryl-S,S-dihydrocarbylsulfilimines by reaction of phenylisocyanate compounds with hydrocarbyl sulfoxides. The sulfilimines can be rearranged to ortho-thioalkylene anilines and the reactions can be employed in a route for converting nitrobenzene compounds to ortho-thioalkylene anilines, which are useful intermediates for preparation of herbicidal compounds.
所披露的过程涉及通过将苯基
异氰酸酯化合物与烃基亚砜反应来制备N-芳基-S,S-二烃基亚磺
酰亚胺。这些亚磺
酰亚胺可以重排为邻-
硫代烷基
苯胺,并且这些反应可以用于将
硝基苯化合物转化为邻-
硫代烷基
苯胺,后者是制备
除草剂化合物的有用中间体。
