Die neuen Brenztraubensäurehydrazone der allgemeinen Formel 1 in der R ein Wasserstoffatom einen gegebenenfalls niederalkylsubstituierten Arylrest oder einen geradkettigen oder verzweigten, gesättigten oder ungesättigten Alkylrest, der durch einen niederen Alkoxy-, Cycloalkyl- oder einen gegebenenfalls niederalkylsubstituierten Arylrest substituiert sein kann und X die Gruppe -A-B- bedeutet, mit der Maßgabe, daß A an das Stickstoffatom und B an den Rest R gebunden sind, wobei A eine geradkettige oder verzweigte Alkylengruppe mit 2-8 Kohlenstoffatomen darstellt, mit einem geradkettigen Teilstück von mindestens 2 Kohlenstoffatomen, das B mit dem Stickstoffatom verbindet, und B ein Sauerstoff- oder ein Schwefelatom bedeuten, sowie deren physiologisch unbedenkliche Salze, Ester und Amide hemmen die Absorption von Glucose aus dem Intestinaltrakt in einem Dosisbereich, in dem die blutzuckersenkende Wirkung noch nicht oder nur unwesentlich auftritt. Die Verbindungen eignen sich daher zur Behandlung von Krankheiten, bei denen nach Aufnahme von kohlenhydrathaltigen Nahrungsmitteln starke und langanhaltende Hyperglykämien auftreten. Verfahren zu ihrer Herstellung werden beschrieben.

摘要:
Compounds of the general formula wherein R 1 , R 2 , R'. R 4 and R 5 are each independently H, Cl, Br. NO 2 or CF 3 ; X = H or Br; and Z is H, CH 3 or CF 3 . The compounds are all potent inhibitors of oxidative phosphorylation in rat liver mitochondria and have other biological activity, for example, insecticidal activity. The compounds are made (A) where X = H and Z = CF 3 . by reacting the appropriately substituted phenylhydrazine with hexafluoroacetone in a basic organic solvent in the presence of an acidic dehydrating agent; (b) where X = H and Z is H or CH 3 by reaction of the phenylhydrazine with 1,1,1-trifluoroacetone or trifluoroacetaldehyde in a suitable solvent in the presence of an acid catalyst: (c) where X = Br can be made from the corresponding compound where X = H by direct bromination. The invention includes insecticidal compositions containing the compounds.
