Heptanoyl chloride

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... 

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... 

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...

The reaction of 10-undecenoic acid [2a], for example, with an acyl chloride such as acetyl chloride, heptanoyl chloride, hexadecanoyl chloride, and EtAlCl2 in a ratio of 1 1 2 in dichloromethane gave the corresponding P,y-unsaturated keto carboxylic acid [5a]-[5c] (Scheme 1) after a reaction time of 2 h at room temperature with high regioselectivity. The products were obtained as a mixture of ( /(Z)-stereoisomers ([( )] [(Z)] = 3 1) in isolated yields of 50-67%. Catalytic hydrogenation of the unsaturated ketocarboxylic acids [5a]-[5c] gave the saturated products in quantitative yields (2). 

The Lewis acid-induced acylation of unsaturated fatty compounds combined with the following reactions allows the synthesis of natural products derived from fats. Acylation of 10-undecenoic acid [2a] with heptanoyl chloride gave 12-oxo-9-octadecenoic acid reduction with NaBHq afforded the racemate of ricinelaidic acid [6], a natural product (Fig. 2).
