Reaction of 2-Polyfluoroacylcyclohexanones with Semicarbazides.-The 2-polyfluoroacylcyclohexanones (I) react with semicarbazide and thiosemicarbazide to give the indazoles (III) with complete regiospecificy and excellent stereoselectivity. Only the reaction of diketone (Ia) with semicarbazide proceeds abnormally to give the semicarbazone (IV). X-ray studies secuse the product structures.-(PASHKEVICH, K. I.; SEVENARD, D.
