ABSTRACT:
Preparing azasulfonium halide salt derivatives of an aniline by reacting a halogen with a non-carbonylic dihydrocarbon sulfide, a beta-carbonylic hydrocarbon sulfide, or a .beta.-thio ester or amide to form a halogen: sulfur compound complex and then reacting the complex with an aniline to form the azasulfonium halide salts. The azasulfonium halide salts are useful as intermediates in processes for making ortho-alkylated anilines, indoles, and 2-oxindoles which have a variety of known uses.
