1,2-Bis(1H-indol-2-yl)ethane (9) has been prepared and converted into indolo[2,3-c]carbazole (8) using palladium acetate in refluxing acetic acid. Reaction of 9 with CoF 3 in hot TFA led to isolation of cyclohept[1,2-b:5,4-b H ]bisindole derivatives 11 and 12, which could be elaborated into further
