Abstract

The chlorination of carbazole with sodium hypochlorite in CH2CI2, CHC13, or CCll gave N- chlorocarbazole in 63-95% yield. It rearranged in refluxing methanol to give carbazole, 3- chlorocarbazole, 1-chlorocarbazole, 3, 6-dichlorocarbazole, and 1, 6-dichlorocarbazole. These chlorocarbazoles were formed in an acid-catalyzed intermolecular reaction. In the presence of potassium carbonate dechlorination of N-chlorocarbazole was observed. No ...
