The chlorination of carbazole with sodium hypochlorite in CH2Cl2, CHCl3, or CCl4 gave N-chlorocarbazole in 63-95percent 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 evidence for an intramolecular rearrangement was found.
