Iron Single‐Atom Catalyzed N‐Alkylation of Amines with Alcohols via Solvent‐Free Borrowing Hydrogen Strategy

Advanced Science, EarlyView.
An innovative iron‐based single‐atom catalyst (FeSA@N‐G) with Fe1–N4 coordination is presented, synthesized through a simple and scalable method. It exhibits exceptional activity and selectivity in N‐alkylation via the borrowing hydrogen strategy under solvent‐free conditions, producing water as the only by‐product. Achieving record TOF (413.1 h-1) and

Synthesis of Primary Amines via Reductive Amination of Aldehydes and Ketones Over a Ni‐Doped MFM‐300(Cr) Catalyst

Advanced Science, EarlyView.
Reductive amination of aldehydes and ketones to primary amines with high selectivity and yield can be achieved over Ni‐doped MFM‐300(Cr) in the presence of NH3 and H2. In situ inelastic neutron scattering, coupled with modeling, reveals that cooperativity between Ni active sites and MFM‐300(Cr) affords an optimal microenvironment for the selective ...

Pd(II)–NHC (NHC = N‐Heterocyclic Carbene)‐Catalyzed Alkylation of Primary Amides by Site‐Selective N─C(O) Activation

Advanced Science, EarlyView.
A highly efficient method for Pd(II)–NHC (NHC = N‐heterocyclic carbene)‐catalyzed alkylation of primary amides using alkyl organozinc reagents is reported. The sterically‐hindered and readily accessible IPr* is found to be privileged for facilitating this highly challenging alkylation. Comparative studies, application to the synthesis of pharmaceutical
