C4-Alkylamination of C4-Halo-1<i>H</i>-1-tritylpyrazoles Using Pd(dba)<sub>2</sub> or CuI
Alkylamino coupling reactions at the C4 positions of 4-halo-1<i>H</i>-1-tritylpyrazoles were investigated using palladium or copper catalysts. The Pd(dba)<sub>2</sub> catalyzed C-N coupling reaction of aryl- or alkylamines, lacking a β-hydrogen atom, proceeded smoothly using...
