Heptamide has been prepared by heating heptanoic add with ammonia in a sealed tube 2 at 230°, by treating heptanoic anhydride with ammonia,3 by passing ammonia through heptanoic acid4 at 125-190°, by the rearrangement of heptaldehyde oxime in the presence of Raney nickel in a quartz tube at 150° for 5 minutes,6 by the Will-gerodt reaction with 2-, 3-, or 4-heptanone or heptanal,6-7 and by the action of ammonia on heptanoyl chloride.8... [Pg.84]

Schmid and Ingold (1978) extended their investigation by allowing pairs of spin traps to compete for n-hexyl radicals (from bis-heptanoyl peroxide). It was emphasized that the error limits in these experiments were large (ca. 30%), since the onset of the decay of certain spin adducts was evident at very low adduct concentrations. [Pg.32]

Other ketones may be reduced by this same procedure. The submitters report that the following have been reduced with yields of 70-90 per cent 0- and p-butyryl phenols, 0- and p-valeryl phenols, 0- and />-caproyl phenols, 0- and />-heptanoyl phenols, 0- and -octanoyl phenols, o- and />-pelargonyl phenols, o- and />-undecylyl phenols. The same procedure applies to acyl resorcinols and acyl chlororesorcinols. Caproyl and octanoyl resorcinols reduce to the corresponding alkyl derivatives in yields of 70-80 per cent. Butyryl, valeryl, caproyl, heptanoyl,... [Pg.30]

In a i-l. three-necked flask fitted with a stirrer (Note i) and a reflux condenser is placed 200 g. of amalgamated mossy zinc (Note 2). A mixture of 200 cc. of water and 200 cc. of concentrated hydrochloric acid is added and then a solution of 60 g. of o-heptanoyl phenol (Note 3) in 100 cc. of alcohol. The mixture is agitated vigorously and refluxed until reduction is complete (Note 4). [Pg.88]

Glutaryl dichloride undergoes reduction at mercury to give 5-chlorovalerolactone and valerolactone a polymeric solid, possibly X[(CH2)3CHCl-0-C=0] (CH2)3X (whereX = CHO or CO2H), is additionally produced [73]. Heptanoyl chloride [71], trimethylacetyl chloride [74], and cyclo-hexanecarbonyl chloride [75] can be reduced at carbon or mercury cathodes to form the corresponding aldehydes in addition, the anhydride (and sometimes... [Pg.225]

Linear sweep voltammetry of ben2x yl chloride in acetonitrile containing tetra-ethylammonium fluoroborate shows Ep == -1.4 V vs. see and for heptanoyl chloride Ep = -2,2 V vs. see [169] The one-electron reduction of acid chlorides at these potentials is a source of carbonyl radicals. Reduction of benzoyl chloride at the peak... [Pg.357]

Uranium(VI) fluoride in l,l,2-trichloro-l,2,2-trifluoroethane at 0°C oxidizes12 aldehydes to acid fluorides in moderate yields (e.g., heptanoyl fluoride from heptaldehyde in 47% yield, benzoyl fluoride from benzaldehyde in 40% yield) benzaldehyde gives methyl benzoate and benzaldehyde dimethyl acetal when the reaction mixture is worked up by quenching with methanol.13... [Pg.683]
