- POLYMERISATION OF INDOLE. PART 3. TWO INDOLYLQUINOLINES, AN INDOLE TETRAMER, AND THE DIHYDRO DERIVATIVE OF THE INDOLE DIMER
-
Treatment of indole (1) with toluene-p-sulphonic acid in Dowtherm A gave the dihydro dimer (7), the indol-3-ylquinoline (8), the indol-2-ylquinoline (10), and the tetramer (19).The indol-3-ylquinoline (8) was also produced on treatment of the 2,3'-trimer (3) with zinc chloride in acetic acid or with toluene-p-sulphonic acid in Dowtherm A.The identification of these products (78), (8), (10), and (19) is described and the mechanisms of formation are discussed.

- POLYMERISATION OF INDOLE. PART 2. A NEW INDOLE TRIMER
-
Treatment of indole (1) with toluene-p-sulphonic acid in benzene provided the 2,3'-indole trimer (4), a positional isomer of the well known 3,3'-indole trimer (3).The structure of the new trimer (4) was established by comparitive studies with the trimers (3) and (4).
