Abstract The pyrazoles (CF 3) 2 C 3 HN 2 R [R= H, COPh, C 6 F 5, C 6 H 4 NO 2-4 and C 6 H 3 (NO 2) 2-2, 4] have been prepared in yields ranging from 27%(R= C 6 F 5) to 78%[R= C 6 H 3 (NO 2) 2-2, 4] by the reaction between 1, 1, 1, 5, 5, 5-hexafluoropentane-2, 4-dione and the appropriately substituted hydrazine, NH 2 NHR.
