Usage

General Description

N-Butylacetanilide, also known as N-butyl-N-phenylacetamide, is a chemical compound commonly used as an intermediate in the production of pharmaceuticals and is also employed as an ingredient in sunscreen products and insect repellents. It is a derivative of acetanilide, which is an organic compound with analgesic and fever-reducing properties. N-Butylacetanilide is a white crystalline powder with a faint odor, and it is sparingly soluble in water but soluble in organic solvents. Its primary use in pharmaceuticals is as a local anesthetic, and it is also utilized as a fragrance and flavoring agent in various cosmetic and personal care products. Additionally, N-Butylacetanilide is considered to be relatively safe for use, with low toxicity and low potential for environmental harm.

Method for promoting acylation of amine or alcohol by carbon dioxide

The invention relates to a method for promoting acylation of amine or alcohol by carbon dioxide, which comprises the following steps of: mixing an amine compound, carboxylate or thiocarboxylate compound and a reaction solvent under the action of carbon dioxide, and reacting to obtain an amide compound, or under the action of carbon dioxide, mixing the alcohol compound, the thiocarboxylate compound and the reaction solvent [gamma]-valerolactone, and reacting to obtain the ester compound. According to the invention, under the promotion action of carbon dioxide, carboxylate or thiocarboxylate is used as an acylation reagent, and amine and alcohol are converted into amide and ester compounds in the absence of a transition metal catalyst, so that acylation reagents such as acyl chloride or anhydride with irritation and corrosivity are avoided; and the method has the advantages of simple operation, mild reaction conditions, high tolerance of substrate functional groups, strong applicability and high yield, and provides an efficient, reliable and economical preparation method for synthesis of amide and ester compounds.

Transition metal-free N-arylation of secondary amides through iodonium salts as aryne precursors

By using a diaryliodonium salt as a benzyne precursor, a transition metal-free approach for N-arylation of secondary amides is developed. This novel benzyne precursor, which can be prepared easily by a one step process from an aryl iodide, shows different reactivities with previous benzyne precursors in the N-arylation reaction. Mechanistic studies confirm the involvement of benzyne species (generated in situ from the diaryliodonium salts) as key intermediates.
