Participants

Reaction Steps

2,4-diphenylthiopyrylium perchlorate (1 g, 2.87 mmole) and aniline (0.54 g, 5.74 mmole) were heated in 10 ml of ethanol at 40° to 45° C. The reaction mixture was immediately colored deep blue. After stirring was continued for two hours, the reaction mixture was allowed to stand at room temperature to give blue needles of 2-(4-aminophenyl)-4,6-diphenylthiopyrylium perchlorate. This compound was recrystallized from a mixture of ethanol-chloroform.
