摘要

The synthesis of 5-trifluoromethyl-1-phenyl-1H-pyrazoles from the reactions of 4-alkoxy-1,1,1-trifluoro-3-alken-2-ones CF3C(O)CH=C(R~1)OR, where R = Me, Et; R~1 = H, Me, Bu, i-Bu, Ph, 4-MeC6H4, 4-FC6H4, 4-ClC6H4, 4-BrC6H4> 4-IC6H4> fur-2-yl with phenyl hydrazine in the presence of ionic liquid BMIMBF4 is reported. Synergic effects of ionic liquid and microwave irradiation in promoting pyrazole synthesis have been shown for the first time.
