The synthesis of esters has become an important industrial methodology over the past years because of the role that they serve in the chemical industry. In this study, we present the use of a novel catalyst for the direct conversion of aldehydes into esters. The yields obtained using supported iron oxide nanoparticle catalysts (FeNP) are very high (>90%). The catalyst is also shown to be very stable as shown by the recyclability study (up to 11 times).

The base-catalyzed reactions of p-fluorobenzoyl chloride provide a convenient method for (19)F NMR analysis of alcohols, phenols, carboxylic acids, amines, and thiols.The (19)F chemical shift and yield data for p-fluorobenzoyl derivatives for nearly 100 compounds are presented.The yield data for these p-fluorobenzoyl derivatives suggest a simple, and in many cases, quantitative method for introducing a fluorine tagging group.The (19)F chemical shifts indicate a wide chemical shift range (ca. 10 ppm) for a large number of compounds.Furthermore, most chemical classes (e.g., phenols, alcohols, etc.) have fairly well resolved chemical shift regions.
