Abstract
Several 3-aryl-1,1,1-trifluoro-4,5-diaza-2,4-alkadienes 3 were synthesized in good yields from arenecarbaldehyde dimethylhydrazones 1 or its trifluoroacetylated derivatives 2 by reaction with an excess of trifluoroacetic anhydride in pyridine. Acid hydrolysis of 3 afforded 1-aryl-3,3,3-trifluoro-1-propanones 4 in high yields.Keywords
