Abstract

Process for the selective N-sulfonylation of oxindoles, in particular process for the N-sulfonylation of 3-triazinyloxindoles, and also N-sulfonyl-substituted 3-triazinyloxindoles and the use of N-sulfonyl-substituted oxindoles and of N-sulfonyl-substituted 3-triazinyloxindoles as intermediates for the synthesis of fine chemicals and of active ingredients in the field of pharmacy and agriculture, and also the use of these compounds as active ingredients in the field of agriculture.
