General Description

Dibutylammonium bromide is a chemical compound with the formula (C4H9)2NH2Br, often used as a phase-transfer catalyst in organic synthesis. It is a quaternary ammonium salt with the cation consisting of two butyl groups attached to the nitrogen atom. Dibutylammonium bromide is a white crystalline powder that is soluble in water and organic solvents. It is commonly used as a catalyst in organic reactions, especially in the synthesis of pharmaceuticals and agrochemicals. Additionally, this compound has applications in the production of specialty chemicals and in the preparation of nanomaterials. It is important to handle dibutylammonium bromide with care, as it is a skin and eye irritant and should be used in a well-ventilated area.

EFFECT OF THE STRUCTURE OF AMINES ON RATE AND MECHANISM OF THEIR REACTIONS WITH 2-(β,β-DIBROMOVINYL)-5-NITROFURAN IN ACETONITRILE

The kinetics of the reaction of 2-(β,β-dibromovinyl)-5-nitrofuran with alkylamines of various types (primary, secondary, and tertiary) in acetonitrile at 55 deg C were studied.It was shown that enamines are formed quantitatively in the case of the reactions with secondary amines.At the same time the products from the reactions with primary amines are the corresponding amidines.Here the monosubstitution product is formed at the first stage, as in the case of the reactions with secondary amines, and rearranges to the imidoyl halide with subsequent substitution of the halogen atom at the imidoyl carbon atom.A quantitative assessment is made of the effect of the structure of the enamine on the rate of the processes.

KINETICS OF THE REACTIONS OF 2-HALOGENOPYRIDINIUM SALTS WITH PRIMARY AND SECONDARY AMINES IN ACETONITRILE

The kinetics of the reactions of 2-halogeno-N-alkylpyridinium salts with primary and secondary aliphatic amines in acetonitrile at 25 deg C were investigated.The reactions obey second-order relationships.In the reaction of 2-bromo-N-ethylpyridinium bromide with aliphatic amines the effect of electronic and steric factors on the reactivity of the amines was examined.
