Yield:6960-42-5 90%

Reaction Conditions:

with C14H22B10Br2FeN2 in toluene at 20; for 4 h;

Steps:

6 The ferrous complex prepared in Example 1 was used as a catalyst to catalyze the synthesis of indole derivatives:

Toluene (toluene) solution of divalent ferrous complex (0.003mmol) was added to 2-nitroaniline (1mmol), then acetaldehyde (1mmol) was added, and the reaction was carried out at room temperature for 240 minutes. After completion, the concentrated reaction solution was directly passed through a silica gel column Chromatographic separation, drying to the same quality, the corresponding indole derivative C8H6N2O2 (yield 90%)
