3H-Perfluoroalk-2-enes react with aqueous ammonia to form polyfluorinated iminoenamines, from which hexafluoroacetylacetone and its analogs were synthesized.
New efficient synthetic routes to trifluoromethyl substituted pyrazoles and corresponding β-diketones
An improved and more efficient synthesis procedure for trifluoromethyl substituted pyrazoles, namely 3,5-bis(trifluoromethyl)-1H-pyrazole (1a), 5-(pentafluoroethyl)-3-(trifluoromethyl)-1H-pyrazole (1b), 5-(heptafluoropropyl)-3-(trifluoromethyl)-1H-pyrazol
