- Abstract
We have successfully accomplished gem‐difluorination of triazole alkyl functionalized amino pyrazoles in the presence of Selectfluor under dry condition and obtained 4,4‐difluoro pyrazol‐3‐imines derivatives in high yield. However, in the presence of water, 4,4‐difluoro pyrazol‐3‐one derivatives were afforded. Gem‐difluorination of triazole alkyl functionalized amino pyrazoles was successfully accomplished in the presence of Selectfluor under dry condition and 4,4‐difluoro pyrazol‐3‐imines derivatives were obtained in high yield.
