The present invention relates to a process for preparing sulfonyl halides comprising the steps of a) reacting an enoxymetal, allylsilane or allylstannane compound, preferably in the presence of a diene, with sulphur dioxide and b) adding a suitable halogen source to the metal sulfinate intermediate of step a). Furthermore, the present invention relates to new sulfonyl chlorides, bromides, and iodides, sulfonamides and sulfonates. In addition, the present invention teaches the use of the new multifunctional sulfonamides and sulfonates for the preparation of a medicament, bacteriocides, fungicides, pesticides, and herbicides as well as the use of sulfonyl chlorides for the preparation of sulfonamides and sulfonates.
本发明涉及一种制备磺酰卤化物的过程,包括以下步骤:a)将enoxymetal、烯丙基硅烷或烯丙基锡化合物与二氧化硫反应,优选在二烯基存在下进行;b)向步骤a)的金属磺酸盐中加入适当的卤素源。此外,本发明还涉及新的磺酰氯化物、溴化物和碘化物、磺酰胺和磺酸盐。此外,本发明还教授了新的多功能磺酰胺和磺酸盐用于制备药物、杀菌剂、杀真菌剂、杀虫剂和除草剂,以及磺酰氯化物用于制备磺酰胺和磺酸盐的用途。
