Reaction Conditions:

with cobalt(II) phthalocyanine;N,N,N,N,-tetramethylethylenediamine in acetonitrile at 60; for 12 h;Schlenk technique;

Steps:

8; 21
Add the substrate phenylhydrazine 0.6mmol (65mg), 2-bromocarbazole 0.2mmol (50mg), cobalt(II) phthalocyanine 11mg (10mol%), TMEDA93mg (4eq.), 2mL acetonitrile to a 50mL Schlenk tube, add magneton, The reaction was stirred at 60°C for 12h. After the reaction is over, add 50 mL of saturated brine, extract three times with 3*50 mL of dichloromethane, add anhydrous sodium sulfate to dry for 30 minutes, and then use a rotary evaporator to remove the low-boiling solvent. After the reaction liquid was vaporized by rotating and passed through the column, the target product was obtained with a yield of 98%.
