2-Chloro and 2-fluoro ketones derived from the chiral-pool
摘要:
Both (2R,5R)- and (2S,SR)-isomers of 2-chloro-2-isopropyl-5-methyl-, 2-chloro-2-methyl-5-isopropyl- and 2-fluoro-2-methyl-5-isopropylcyclohexanones have been synthesized and fully characterized. It is shown that a rapid overview of the H-1 NMR spectrum allows an unambiguous assignment of the axial or equatorial position of the halogen atom and that the IR VCO absorption does not differ from one isomer to the other.

Iron(III) chloride-catalysedphoto-oxidation of substituted olefins gave either gem-dichloro-ketones or α,ω-dichloro-ketones selectively, depending upon the substitution pattern of the substrates.
