A new facile synthesis of orderedmesoporousaluminosilicates has been developed and applied for the efficient catalytic synthesis of N‐benzyl secondary amines under ligand and base‐free conditions. The MAS(38) catalyst with a well‐orderedmesoporous structure and strong acidic sites was used for acid‐catalyzed organic transformations and its operational simplicity and ease of its isolation procedure

The Co–N coordination in CoNx@NC (NCN-doped carbon) was found to be beneficial in producing high conversion efficiency and high yield for secondary amines in the N-alkylation reaction between alcohol and aniline.
a reusable catalyst for C-/N-alkylation of alcohols with higher reaction efficiency and selectivity compared to individual components via its flexible binding sites, diverse hydrogen bond donor-acceptor fragments, rigidity, variable coordination mode, and cooperativity.

A facile and efficient method for Ullmann-type C-N coupling reaction of amine and aryl halide catalyzed by CuI/metformin in EtOH is described. The advantages of this method are the use of an inexpensive and readily available catalyst and ligand, easy workup, shorter reaction time, improved yields, and the use of green solvent. Furthermore, this procedure is applied successfully for the modification of natural products, such as Vindoline and Tabersonin. (C) 2014 Elsevier Ltd. All rights reserved.

amines (11 examples) were yielded by using nitroarenes as a nitrogen source and benzaldehyde in the presence of the mpg-C3N4/AgPd nanocatalyst, which is the first example in the literature. Monodisperse AgPd alloy NPs (2.5 ± 0.5 nm) were synthesized by using our established protocol via the co-reduction of silver(I) acetate and palladium(II) acetylacetonate in the presence of oleylamine and oleic acid
