The method includes polishing the surface using a polishing pad, water, abrasive particles, and an organic compound having both a carboxylic acid functional group and a second functional group selected from amines and halides. The abrasive particles can be dispersed in the aqueous medium or they ...
Derivatives of 2-, 3-, and 4-aminobenzoic acid were synthesized by adding aromatic halides to the stirred solution of aminobenzoic acids in pyridine. For benzyl-based derivatives, the reaction mixture was refluxed for more than 24 h [52]. 4-aminobenzohydrazide compounds were synthesized from 4...
Highly reactive acid derivatives such as acid halides are easily obtained by mixing with halogenation agents like phosphorus chlorides or thionyl chloride. Ortho esters can be obtained by the reaction of alcohols under acidic water free conditions with benzonitrile. ...
2.1.2.3Acid Halides from Acid Anhydrides Acid anhydridesas activated derivatives of carboxylic acids have found little attention for the preparation of acidhalides. Their use can be justified if they are obtained from other sources than from carboxylic acids,e.g.phthalic anhydridefrom the oxidation of...
(Fig.2a). The functional group tolerance of the reaction is of broad. Both electron-donating and electron-withdrawing groups, such as alkyl, alkoxyl, [1,3]-dioxol, F-, Cl-, Br-, CF3-, MeO2C-, sulfonyl, and even coordinative cyano-, were compatible under the conditions (2b-2o). ...
Important carboxylic-acid derivatives include esters, anhydrides, amides, halides (see halogen), and salts (see soap).acetylcholine Summary Acetylcholine, an ester of choline and acetic acid that serves as a transmitter substance of nerve impulses within the central and peripheral nervous systems. ...

Deuterated carboxylic acids can undergo numerous functional group interconversions to access alcohols, alkyl halides thiols, amides, esters, amines and other relevant functional groups through standard organic chemistry techniques. For instance, deuterated fatty acids serve as the precursors for synthesis of...
There have been few reports of nucleophilic sulfenic acid addition to different activated and unactivated alkyl halides as well (Fig. 4, reaction 5) [15,28–30]. In the end, it must be emphasized that even though sulfenic acids show greater variety of nucleophilic than electrophilic reactions,...
