A rapid and efficient procedure is developed for a one-pot synthesis of nitriles by
condensation of aldehydes with hydroxylamine hydrochloride in the presence of
P2O5/SiO2 in solvent-free media under microwave irradiation....
Fe(HSO4)3-Catalyzed Direct Conversion of Aldehydes into Nitriles Using Hydroxylamine Hydrochloride
Due to the importance and various applications of nitriles, especially in medicinal productions, a new method for conversion of aldehydes to nitriles has been presented. Several nitrile-containing aromatic compounds were synthesized through...
An efficient method for the conversion of aldehydes to nitriles in the presence of sulfamic acid as catalyst
intermediate for various agricultural chemicals, dyes,
material sciences and as intermediates in microbial metabolism.
Nitriles are important starting materials for the preparation of amines, amides, carboxylic acids, aldehydes...
Solvent-Free Oxidations of Alcohols, Oximes, Aldehydes and Cyclic Acetals by Pyridinium Chlorochromate
Oxidative transformations of alcohols, oximes and cyclic acetals to carbonyl compounds proceed efficiently by pyridinium chlorochromate (PCC) under solvent-free conditions. The oxidation of aromatic and cinnamylic aldehydes to carboxylic acids...
One-pot Synthesis of Benzimidazoles and Benzothiazoles in the Presence of Fe(HSO4)3 as a New and Efficient Oxidant
A series of substituted benzimidazoles and benzothiazoles were prepared through the one-pot reaction of ophenylenediamine and o-aminothiophenol with various aldehydes in the presence of ferric hydrogensulfate
