A reaction reinvestigation of fluorinated 1,3-dicarbonyl compounds with NaNO2 in acidic conditions revealed the formation of corresponding 1,1,1-trifluoro-3-hydroxyimino-butan-2,4-diones which predominantly isolated as hydrates. A novel synthesis of ethoxy-, alkyl-, (het)aryl substituted carbonylcyanides via acid-catalyzed detrifluoroacetylation of obtained 2-hydroxyimino derivatives of 1,3-dicarbonyl
