TABLE 4: MAGNETIC MOMENTS (B.M) AND g – VALUE OF Mn (II) coMPLEXES OF 2-HEPTANONE SEMICARBAZONE AND 2-HEPTANONE THIOSEMICARBAZONE

6-Methyl-6-hydroxy-2-hepta-none was dehydrated to 6-methyl-5-hepten-2-one with a trace of iodine.

9.31Ketones such as 2-heptanone may be readily prepared by hydration of terminal alkynes. Thus, if we had 1-heptyne, it could be converted to 2-heptanone.

synthesis of 2 heptanone - The first one of that.

Stereoselective reductive metabolism of ketones in rabbit-liver cytosol.

6-Methyl-6-hydroxy-2-heptanone, reported by Verley in 1897, which was obtained by the hydration of methyl heptenone with 40-50% H2SO4, differed apparently from the hydrolygate of 6-methyl-6-hydroxy-2-heptanone acetate.

Kinetic evaluation of binding and activation parameters controlling the catalytic cycles of unbranched, acyclic secondary alcohols and ketones as substrates of the native and active-site-specific Co(II)-substituted enzyme.

TABLE 6: LIGAND FIELD PARAMETERS OF Mn(II) COMPLEXES OF 2-HEPTANONE SEMICARBAZONE AND 2-HEPTANONE THIOSEMICARBAZONE

When 6-methyl-5-hydroxy-2-heptanone acetate was hydrolyged with alcoholic sodium hydroxide solution, 2-isopropyl-5-methyl-5-ethoxy-tetrahydrof uran and 6-methyl-5-hydroxy-2-heptanone were obtained.

The dehydration of 6-methyl-5-hydroxy-2-heptanone was best carried out at 280-370°c by passing through a pyrex glass tube, packed with pumice catalyst containing phosphoric acid.

One-step synthesis of 2-pentanone from ethanol over K …

Synthesis of ligand L2: An ethanolic solution of thiosemicarbazide (0.91g,0.01mol) and ethanolic solution of the 2-heptanone 1.42ml, 0.01 mol were mixed together in equimolar (1:1) ratio a small amount of glacial acetic acid was added and the contents were refluxed on a water bath for about one hour and then concentrated. On cooling in an ice bath yellowish coloured thiosemicarbazone separated out. Analytical data of the ligands L1 and L2 are given in table 1.

Synthesis of the Complexes: An ethanolic solution of the corresponding ligand (0.1 mol) was mixed with (0.05 mol) of aqueous solution of manganese salt (chloride, acetate, chlorate, thiocynate). The mixture was shaken thoroughly, refluxed for about 1 to 2 hour on a water bath and then cooled, when white crystals appeared. The separated crystals were filtered, washed with 50% ethanol, and finally dried at 60oC in an electric oven. Analytical data for the complexes are given in Table 2.

Synthesis of 4-methyl-3-heptanol and 4-methyl-3-heptanone

RESULTS AND DISCUSSION: The complexes were synthesized by reacting ligands with the metal ions in 2:1 ratio in ethanolic medium .the ligands behaves as bidentate coordinate through sulphur/ oxygen and nitrogen donor atoms. The analytic data, magnetic susceptibility, and spectral analysis agree well with the proposed composition of formed complexes. All the complexes have shown good solubility in DMSO.

3-bromo-2-heptanone | C7H13BrO - ChemSynthesis

Synthesis of ligand L1: Ethanolic solution of 0.01 mole semicarbazide hydrochloride (1.11g) and 0.01mole of sodium acetate (0.82g) were dissolved in 50 ml of distilled water and 0.01 mole of 2-heptanone (1.42ml) was added to it.50 ml of alcohol was added to this mixture, the reacting mix shaken thoroughly and refluxed for about an hour on a water bath. On cooling, white crystalline semicarbazone separated out. It was filtered washed with ethanol and dried over P4O10.
