By exploiting hetero-complementary aromatic oligoamide units containing hextuple hydrogen bonds, supramolecular graft copolymers were successfully constructed in moderately polar media.
A novel, general route to the synthesis of carboxylic acid esters and thiolesters
Sucheta,Reddy,Ravi,Rama Rao
, p. 4415 - 4416 (2007/10/02)
Carboxylic acids were conveniently esterified with alcohols and thiols by the use of triphenylphosphine and N-bromo/Iodo succinimide to afford the corresponding esters and thiol esters.
REAGENTS AND SYNTHETIC METHODS 28. MODIFIED PROCEDURES FOR ANHYDRIZATION, ESTERIFICATION AND THIOLESTERIFICATION OF CARBOXYLIC ACIDS BY MEANS OF AVAILABLE PHOSPHORUS REAGENTS.

Carboxylic acid anhydrides, esters and thiol esters are obtained by a one-pot method from carboxylic acids and alcohols or thiol by means of phosphorus oxychloride or phenyl dichlorophosphoridate reagents.
Esterification of Aromatic Carboxylic Acids with Alcohols Using 2-Chloro-3,5-dinitropyridine as a Condensing Agent
Takimoto, Seiji,Abe, Naomi,Kodera, Yasushi,Ohta, Hiroshi
, p. 639 - 640 (2007/10/02)
The reaction of 2-chloro-3,5-dinitropyridine (CDNP) with carboxylic acids and alcohols was examined, and it was found that CDNP was a useful condensing agent.Various esters were prepared in good yields.
Esterification of Carboxylic Acids with Alcohols Using Benzenesulphonyl and Methanesulphonyl Chlorides

The role of benzene- and methane-sulphonyl chlorides as coupling agents in the esterification of carboxylic acids with alcohols has been investigated.Hindered tertiary alcohols require initial conversion of the acid to the mixed acid-anhydride with benzenesulphonyl chloride.It is necessary to adjust molar ratios for esterification with secondary alcohols so that the intermediate formed is the symmetrical acid anhydride, since mixed acid-anhydrides also give the sulphonates of the alcohols wihich are difficult to separate from the esters.
Esterification of Carboxylic Acids by Alcohols with 2-Chloro-1,3,5-trinitrobenzene as Condensing Agent

When mixtures of carboxylic acids or their sodium salts and alcohols were treatment with 2-chloro-1,3,5-trinitrobenzene in the presence of pyridine under mild conditions, the corresponding carboxylic esters were formed.The yields and the rates of the ester formation depended on the types of the acids and the alcohols used.
