We have developed a Br?nsted acid mediated synthetic method to directly cleave stable amide C?N bonds by a variety of alcohol and amine nucleophiles. Reverse reactivity was observed and alcoholysis of amides by activated primary and secondary benzylic, and propargylic alcohols have been achieved instead of the expected nucleophilic substitution of alcohols. As an application, 2-substituted benzothiazole derivatives have been synthesized in one pot employing 2-aminothiophenol as nucleophile.
Metal-free aerobic oxidative esterification of aromatic aldehydes promoted by potassium fluoride (KF)

We investigated the oxidative esterification of aldehydes with alcohols/phenols to produce a range of esters. In this approach, we conducted the reaction under metal-free conditions at room temperature. The reactions were promoted by potassium fluoride (KF) as the additive, resulting in the desired product in good to high yields. This procedure was found to be effective for the production of aryl esters, which are challenging in most of the available reports. It is vital for this procedure not to exclude air as the source of oxygen.
Single-step conversion of electron-deficient aldehydes into the corresponding esters in aqueous alcohols in the presence of iodine and sodium nitrite

experimental part, p. 276 - 282 (2010/03/26)
The direct conversion of aldehydes into their corresponding esters in the presence of iodine and sodium nitrite in aqueous alcohols is reported. In all these reactions, alcohol serves as reactant and also as reaction medium. Almost quantitative yields were obtained with aldehydes containing electron-withdrawing substituents and heterocyclic aldehydes. Georg Thieme Verlag Stuttgart.
EFFECTS OF BRANCHING OF THE ALKYL CHAIN ON THE LIQUID CRYSTALLINE PROPERTIES OF N-(p-PHENYLBENZYLIDENE)-p-ALKOXYCARBONYLANILINES.
Matsunaga,Miyajima

The liquid crystal behavior of twenty-three N-(p-phenylbenzylidene)-p-alkoxycarbonylanilines has been examined by optical microscopy and differential scanning calorimetry in order to study the effects of branching of the alkyl groups.
