where X = H, Me and OMe. To a 100-mL round-bottom flask equipped with a stirring bar were added free-base corrole H3[TpXPC] (0.1355 mmol) and DDQ (0.1355 mmol) and the mixture was dissolved in dichloromethane (20 mL). Upon stirring for 10 min at room temperature, 4aminotriazole (5 equiv, 0.6778 mmol, dissolved in 1 mL DMSO) and KOH (200 mg) were added, and the reaction mixture was stirred overnight at room temperature. At that point, the reaction was judged complete, based on HRMS and UV-vis-NIR analyses of the reaction mixture. Distilled water (20 mL) was added and the reaction mixture was stirred for 1 h to transfer the DDQ to the aqueous phase. The organic phase was separated and washed with water (20 mL x 2). The purple organic phase containing the product was then dried over anhydrous sodium sulfate, the solvent was removed by rotary evaporation, and the residue was purified via column chromatography a silica gel column using 3:2 hexane/dichloromethane as the mobile phase. The eluate, upon rotary evaporation, yielded the desired product as a purple solid in 49 to 68 % yield. Analytical data for H2[X-AHP], where X = H, Me and OMe, are as follows.
