97.8% | at 100℃; | In a three-necked flask equipped with a reflux tube, 292 g (1.0 mol) of p-tert-butyl o-dibromobenzene was added.Potassium ferricyanide 329 g (1.0 mol), DBU 1460 mL, silver carbonate 16.8 g (0.1 mol) and copper acetylacetonate 52.4 g (0.2 mol),The reaction was heated to 100° C. After the reaction was over, insoluble material was filtered off and the DBU was recovered under reduced pressure. The residue was poured into water and filtered to obtain 180 g of p-tert-butylphthalonitrile, with a yield of 97.8percent and a purity of 99.0percent. |

51.6% | at 100℃; | In a three-necked flask equipped with a reflux tube, 292 g (1.0 mol) of p-tert-butyl o-dibromobenzene, 90 g (1.0 mol) of cuprous cyanide, 16.8 g (0.1 mol) of silver carbonate, and 52.4 g of copper acetylacetonate (0.2percent) were added. 1460 mL of mol) and DBU were heated to 100 °C. After the reaction, the insoluble material was filtered off and the DBU was recovered under reduced pressure. The residue was poured into water and filtered to give 95 g of p-tert-butylphthalonitrile. The yield was 51.6percent. |
