Reaction of carbazole derivatives with anhydrous ferric chloride (letter to the editor).
J Heterocyclic Chem 1971 Apr; 8(2):333-335
The reaction of carbazole derivatives with anhydrous ferric chloride in organic solvents offers many interesting possibilities for analytical and synthetic studies with these heterocyclics. Intensely colored, stable complexes readily result from these reactions. The results of preliminary studies in this area are presented in this letter.
