Yield:1121-89-7 98%
Reaction Conditions:
with manganese(II) triflate;4,4'-diamino-2,2'-bipyridyl;dihydrogen peroxide in acetone at 20; for 1 h;Reagent/catalyst;
Steps:
1 Example 1
5.59 mg (0.03 mmol) of 4,4'-diamino-2,2'-bipyridine (Ligand), 5.30 mg (0.015 mmol) of manganese (II) triflate (Mn(OTf) 2),1.5 mL of acetone was added to the reaction tube, and the reaction was stirred at 70 ° C for 10 min.Cool to room temperature and add 49.57 mg (0.5 mmol) of 2-piperidone.Then, 250 μL of 30% by mass of hydrogen peroxide was diluted with 0.5 mL of acetone and then added to the reaction tube through a flow injection pump for 60 minutes.After the addition, saturated sodium sulfite was added to the reaction solution to quench the remaining hydrogen peroxide.Extraction with ethyl acetate gave 1,2-dipiperidone in a yield of 98%.
