Something borrowed: Amine cross‐coupling reactions are catalyzed using [Cp*IrI2}2] (Cp*=C5Me5) in the absence of a base. A range of anilines were converted into their N‐isopropyl derivatives, and the same process was also effective for alkylation of benzylamines and other aliphatic primary amines.

Alkylation of Amines with Alcohols and Amines by a Single Catalyst under Mild Conditions
An efficient catalytic system for the alkylation of amines with either alcohols or amines undermildconditions has been developed, using cyclometallated iridium complexes as catalysts. The method has broad substrate scope, allowing for the synthesis of a diverse range of secondary and tertiary amines with good to excellent yields. By controlling the ratio of substrates, both mono‐ and bis‐alkylated

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

requirements of Buchwald–Hartwigaminations at room temperature. This ligand class combines a strong electron‐donating ability comparable to NHC ligands with high steric demand similar to biaryl phosphines. The active Pd species are stabilized by agostic C−H⋅⋅⋅Pd rather than by Pd–arene interactions. The practical advantage of YPhos ligands arises from their easy and scalable synthesis from widely available
