Acid halide, naming

Halogenwasserstoff, m. hydrogen halide. -sSure, /. halogen hydracid, hydrohalic acid (general name for hydrochloric acid, hydro-bromic acid, etc.), -verbindung, /. hydrogen halide. 

Acid halides are named by identifying first the acyl group and then the halide. The acyl group name is derived from the carboxylic acid name by replacing the -ic acid ending with -yl or the -carboxylic acid ending with -carbonyl, as described previously in Section 20.1 and shown in Table 20.1 on page 753. For example ... 

Cationic condensation products, namely, the reaction products of a dicarboxylic acid or an ester or acid halide thereof and an aminoalkylamine, that are quatemized are recommended for breaking cmde oil emulsions from fireflooding [365],... 

Acid chlorides (or acyl chlorides) result from substituting a chlorine for the hydroxy group of a carboxylic acid. Although other acid halides also exist, they are seldom encountered. Acid chlorides are named by replacing the -ic acid of the carboxylic acid name (either common or systematic) with -yl chloride. 

An acid halide is named by replacing the -ic acid suffix of the acid name (either the common name or the IUPAC name) with -yl and the halide name. For acids that are named as alkanecarboxylic acids, the acid chlorides are named by using the suffix... 

The acyl halides, sometimes called acid halides, are structurally related to carboxylic acids by the replacement of the —OH group by a halogen, most often —Cl. They are usually named by combining the stems of the common names of the carboxylic acids with the suffix -yl and then adding the name of the halide ion. Examples are... 

Besides co-halo- and co-hydroxyalkyl-substituted phosphorus compounds, both C- and P-acid chlorides of mixed phosphonoalkyl-substituted carboxylic acids are inclined to intramolecular cyclization, yielding intracyclic anhydrides of these acids, namely 2,5-dioxo-l,2-oxaphospholanes 78 (Scheme 46) [100-103], Reasonably, C-acid halides undergo cyclization more rapidly than their P-analogues. Moreover, as... 

Carboxylic acid anhydrides have been determined via estimation of the water consumed in an analogous reaction but only two examples could be found for a sulphonyl halide, namely p-acetylaminobenzenesulphonyl chloride, where excess water was back-titrated with the Karl Fischer reagent245,246. 

Acid halides are named by changing the ending of the name of the corresponding acid from -ic acid to -yl halide-, acid anhydrides are named by replacing the word acid by anhydride. 

Acyl halide (Section 15.7) Also called an acid halide. A general name for compounds with the structure RCOX or ArCOX. 

Reductive elimination to form carbon-heteroatom bonds from acyl complexes occurs more readily than it does from alkyl or aryl complexes. This fast rate is consistent with the trends noted previously—namely, reductive elimination is faster from complexes containing groups that are sp hybridized, that are electrophilic, and that can coordinate to the metal center during tiie reductive elimination. Reductive elimination of acid halides has been proposed as a step in the Monsanto acetic acid process, and experimental evidence has been obtained for this type of reductive elinunation from acetylrhodium halide complexes generated in solution (Equation 8.66). - A closely related incorporation of KZO into add halides catalyzed by Wilkinson s catalyst provides further evidence for reversible addition and elimination of add halides involving Rh(I) and Rh(III), respectively. ...
