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。
