Ketones

- 1,2-Halogen migration in haloallenyl ketones: regiodivergent synthesis of halofurans. Selective 1,2-iodine, bromine, and chlorine migration in haloallenyl ketones in the presence of Au catalyst has been demonstrated. It was found that,...

- An efficient and chemoselective iron catalyst for the hydrogenation of ketones.

- An improved method of analysing 2,5-hexanedione in urine. A short gas-chromatographic method for analysing urinary concentrations of 2,5-hexanedione is based on acid hydrolysis of urine at pH below 0.1 and...

- Carbon-11 labeled dialkylketones: synthesis of 9-[11C]heptadecan-9-one. 9-[11C]heptadecan-9-one was synthesized from di-n-octylthexylborane via cyanidation with K11CN. The rearrangement of the organoborane intermediate followed...

- Chemically induced anion radical cycloadditions: intramolecular cyclobutanation of bis(enones) via homogeneous electron transfer. The first examples of anion radical cycloaddition induced by homogeneous electron transfer from chemical agents are described. Specifically, upon exposure to...

- Chromatography of some 2,4-dinitrophenylhydrazones in acid systems.

- Rhodium-catalyzed intramolecular C-H insertion of alpha-aryl-alpha-diazo ketones. Direct diazo transfer proceeds smoothly with alpha-aryl ketones. The derived alpha-aryl-alpha-diazo ketones cyclize efficiently with Rh catalysis to give the...

- Separation of homologous series of 2,4-dinitrophenyl-osazones by column partition chromatography.

- Spectrophotometric determination of ketones by borohydride reduction.

- THIN-LAYER CHROMATOGRAPHY OF ALIPHATIC 2,4-DINITROPHENYLHYDRAZONES.
