General Description

N-butyl-4-chloroaniline, also known as 4-chloro-N-butylaniline, is a chemical compound with the molecular formula C10H14ClN. It is an organic compound that belongs to the group of aniline derivatives, which are commonly used in the manufacturing of dyes and pharmaceuticals. N-butyl-4-chloroaniline is a pale yellow to brown liquid with a characteristic odor, and it is primarily used as an intermediate in the production of dyes and pigments. It is also used as a raw material in the synthesis of agricultural chemicals and pharmaceuticals. However, the compound poses various hazards if not handled properly, as it is harmful if swallowed, inhaled, or absorbed through the skin, and may cause skin and eye irritation. Therefore, appropriate safety measures and protective equipment should be used when handling N-butyl-4-chloroaniline.

Halogenated method of aromatic compound

The invention belongs to the field of organic synthesis, and particularly relates to synthesis of aromatic halogens, in particular to arylamine. The invention discloses a synthesis method of a corresponding ortho-halogenated product from aromatic compounds such as carbazole and phenol. The method comprises the following steps: adding a metal sulfonate salt catalyst, aromatic amine, carbazole, phenol and other hydrogen - heteroatom-containing aromatic compound reaction substrates, a halogenation reagent and a reaction solvent at a specific reaction temperature. After the drying agent is dried, the yield of the reaction product and the nuclear magnetic characterization determining structure are determined by column chromatography. The reaction product yield is determined by gas chromatography. By adopting the method, under the cheap metal salt catalyst, a plurality of ortho-substituted brominated and chloro products can be obtained with moderate to excellent yield.

Practical Singly and Doubly Electrophilic Aminating Agents: A New, More Sustainable Platform for Carbon-Nitrogen Bond Formation

Given the importance of amines in a large number of biologically active natural products, active pharmaceutical ingredients, agrochemicals, and functional materials, the development of efficient C-N bond-forming methods with wide substrate scope continues to be at the frontier of research in synthetic organic chemistry. Here, we present a general and fundamentally new synthetic approach for the direct, transition-metal-free preparation of symmetrical and unsymmetrical diaryl-, arylalkyl-, and dialkylamines that relies on the facile single or double addition of readily available C-nucleophiles to the nitrogen atom of bench-stable electrophilic aminating agents. Practical single and double polarity reversal (i.e., umpolung) of the nitrogen atom is achieved using sterically and electronically tunable ketomalonate-derived imines and oximes. Overall, this novel approach represents an operationally simple, scalable, and environmentally friendly alternative to transition-metal-catalyzed C-N cross-coupling methods that are currently used to access structurally diverse secondary amines.

Functionalized ionic liquids based on imidazolium cation: Synthesis, characterization and catalytic activity for N-alkylation reaction

The novel functionalized ionic liquids based on imidazolium cation are synthesized and characterized by studying its 1H, 13C, and 31P NMR and elemental analysis. These ionic liquids have been reported as a highly efficient catalyst for N-alkylation reaction of aniline with butyl chloride. The reaction was efficiently performed in ionic liquid as an environmentally benign solvent with good yields without transition metal.
