基本信息
| 应用 | Potassium tricyanomethanide is a precursor used for the preparation of dicyano ketene aminals. It reacts with amines to prepare alkyl ammonium tricyanomethanide. Further, it is involved in the preparation of tricyanomethanide-bridged binuclear organometallic complexes such as Cp(dppe)FeC(CN)3 and Cp(PPh3)2RuC(CN)3. It is used as starting material utilized in the preparation of 5-Amino-3-bromo-1-(tert-butyl)-1H-pyrazole-4-carbonitrile, which undergoes sandmeyer reaction to get the corresponding diaminopyrazole, 5-amino-3-aryl-1-(tert-butyl)-1H-pyrazole-4-carboxamides. |
