三氰基甲烷化钾

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.

Incompatible with strong oxidizing agents, acids and ammonia.
