Abstract
AbstractA silver‐catalyzed regioselective one‐pot cyclization reaction of diazo reagents with fluoronitroalkenes was developed. This transformation presents a method for accessing a series of 4‐aryl‐3‐fluoropyrazoles that are substituted with various groups such as trifluoromethyl, carboxylic ester, nitrile, and phosphonate ester. Further synthetic transformations offered the corresponding fluorinated and trifluoromethylated analogues of two fungicide compounds.
