The N‐alkylation of amines or ammonia with alcohols is a valuable route for the synthesis of N‐alkyl amines. However, as a potentially clean and economic choice for N‐alkyl amine synthesis, non‐noble metal catalysts with high activity and good selectivity are rarely reported. Normally, they are severely limited due to low activity and poor generality. Herein, a simple NiCuFeOx catalyst was designed

chelating alkylphosphines for the amination of heteroaryl and aryl chlorides, bromides, and iodides. In the presence of this catalyst, aryl and heteroarylchlorides, bromides, and iodides react with many primary amines in high yields with part-per-million quantities of palladium precursor and ligand. Many reactions of primary amines with both heteroaryl and aryl chlorides, bromides, and iodides occur to

N-Alkylaminobenzenes were prepared in a simple and
efficient one-pot synthesis by reduction of nitrobenzenes followed by
reductive amination with decaborane (B10H14) in the
presence of 10% Pd/C.

We report a diverse demonstration of synthetically useful chemoselectivity in the synthesis of di-, tri-, and tetraamines (62 examples) by use of Buchwald–Hartwig amination employing a single catalyst system ([Pd(cinnamyl)Cl]2/L1; L1 = N-(2-(di(1-adamantyl)phosphino)phenyl)morpholine, Mor-DalPhos). Competition reactions established the following relative preference of this catalyst system for amine
A General Procedure to Selectively Prepare<i>N</i>-Alkylanilines by an Unexpected Reaction of (<i>Z</i>)-(<i>tert</i>-Butylsulfanyl)(aryl)diazenes with Alkyllithium Reagents
has been set up to prepare, selectively, the N-monoalkylanilines 7, reacting (Z)-(tert-butylsulfanyl)(aryl)diazenes 3 with alkyllithium 6 (MeLi, BuLi, s-BuLi, n-C 6 H 1 3 Li). The reactions were carried out in anhydrous diethyl ether at 0 °C or -78 °C, depending on the reagent 6, and then at room temperature. In optimal conditions the yields of the pure products 7 (uncontaminated by dialkylation products)
