M-Caproic anhydride has been prepared by heating caproic acid with acetic anhydride,3 by heating sodium caproate and acetic anhydride in a sealed tube,4 by the action of phosphorus oxychloride on barium caproate,6 by the action of acetyl chloride on caproic acid,6 and by treating a mixture of sodium caproate and sulfur with chlorine.7 The method used in the present synthesis was first described by Hurd and Dull.8...

Direct bromination of an acid yields the a-substituted product when red phosphorus or phosphorus halides are used as carriers. The procedure is illustrated by the preparation of a-bromo-n-caproic acid (89%) and a-bromoisovaleric acid (89%)." An excellent laboratory preparation of bromoacetic acid is furnished by a modification of the reaction in which acetic anhydride with pyridine is used as the catalyst. ... 

Pyridine is used in catalytic amounts and acylpyridinium salts are assumed to be the reactive acylating agents. The method can be applied to the synthesis of both symmetrical and unsymmetrical acid anhydrides. " These can also be obtained in many cases directly from the acid halide and the sodium carbox-ylate without using a solvent or a catalyst. Tiiis approach has been described for a number of mixed acid anhydrides. Thus acetic palmitic anhydride (70%), butyric myristic anhydride (81%) and caproic lauric anhydride (85%) were prepared by heating the components for 2 h at 90 °C. 75 These anhydrides were successfully employed for the N-acylation of amino sugars. 7 ... 

This is an unsymmetrical anhydride. The I.U.P.A.C. names of the two parent carboxylic acids are ethanoic acid (two-carbon) and hexanoic acid (six-carbon). To name an unsymmetrical anhydride, the term anhydride is preceded by the names of the two parent acids. The I.U.P.A.C. name of this compound is ethanoic hexanoic anhydride. The common names of the two parent carboxylic acids are acetic acid and caproic acid. Thus, the common name of this compound is acetic caproic anhydride. 

The reaction has been extended to the acylation of di-f-butylamine with silico anhydrides of acetic, butyric and caproic acids. Ethylamine 2ilso reacts readily with these reagents.
