Versuchsvorschrift

To an ice cold solution of (4-isopropyl-phenyl)-(2-nitro-5-propargyloxy-phenyl)-methanol in 200 ml acetone are added dropwise 60 ml Jones reagent. After stirring for 2 h at rt the reaction is quenched by the addition of isopropanol and sodium bisulfite solution (40%). Extraction with dichloromethane affords (4-isopropyl-phenyl)-(2-nitro-5-propargyloxy-phenyl)-methanone.
