Heptanoic anhydride

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]

Heptanoyl chloride Heptanoic acid Heptanoic anhydride (78-83%) ... [Pg.820]

Acid chlorides are useful precursors to anhydrides, including both symmetrical and mixed (unsymmetrical) anhydrides. In one experiment, heptanoyl chloride (50) reacted with heptanoic acid (51), with benzene as a solvent and in the presence of pyridine (53), to give the symmetrical heptanoic anhydride (53) in 83% isolated yield. Unsymmetrical anhydrides are prepared by choosing which half of the anhydride comes from the acid chloride and which comes from the carboxylic acid. This choice allows one to control formation of the mixed anhydride. If heptanoyl chloride (50) and butanoic acid (7) react in the presence of triethylamine as the base, anhydride 54 is formed. Anhydride 54 can also be prepared by the reaction of butanoyl chloride with hexanoic acid, but the easiest to obtain and cheapest combination is usually used. [Pg.958]
