Background and Objectives: Primary Aromatic Amines (PAAs) are contaminants that can migrate from food flexible packaging. The main origin of these compounds is polyurethane adhesives used in the laminating process of multilayer films. Residual aromatic di-isocyanates of the reaction of adhesive polymerization migrate into the food, and are hydrolyzed to PAAs by the moisture of food. 2,4- and 2,...

An enzyme-mimetic nanozyme system is reported that significantly promotes the oxidative deamination of primary amines. This work gives an example valorization 5-hydroxymethylfurfurylamine and glutamic acid, could be applied to any amino acid after optimization reaction conditions.

Aliphatic allylamines are widely used for the synthesis of diverse building blocks agrochemicals and pharmaceuticals; there is therefore considerable interest in developing versatile direct routes to aliphatic using common chemical feedstocks—olefins amines. However, examples such coupling reactions remain limited. It even more challenging achieve this goal with precise site control. Here we re...

The direct reductive amination of carbonyl compounds with NH3 and H2 is an alternative route to produce primary amines in practical production. The search for efficient and selective catalysts has attracted great interest. In the present work, the reductive amination of heptaldehyde with NH3 was investigated over a Ru-based catalyst. The product selectivities were found to be related with the s...
