Conclusions

  1. 1.

    12, 15-Dihydro-12, 15-dioxo-13, 14-benzotrypticene (I) is polarographically and chemically reversibly reduced on a dropping mercury cathode in dimethylformamide medium and in a mixture of ethanol and toluene against a. background of 0.1 N LiCl.

  2. 2.

    A difference in the mechanism of the reduction of the quinone (I) in the investigated media was demonstrated: in dimethylformamide the reduction proceeds through a stage of semiquinone formation (half-wave potentials equal to E1/2 I =−87 mV; E1/2 II =−472 mV); in an ethanol-toluene mixture, the reduction proceeds in one step (E1/2 =−502 mV). The constants of the diffusion current are equal to 2.62 and 3.04, respectively.
