Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Anomeric Amide‐Enabled Alkene‐Arene and Alkene‐Alkene Aminative Coupling

Angewandte Chemie International Edition
AbstractDespite the prominence of C−N bond forming cross‐coupling reactions as a strategy to assemble molecular fragments, aminative coupling approaches, in which two fragments are assembled directly at the heteroatom, represents a rarely exploited retrosynthetic strategy. Herein, we report the design, synthesis, and implementation of an anomeric amide

Alkene Transfer Hydrogenation with Alkaline-Earth Metal Catalysts.

Angewandte Chemie, 2019
The alkene transfer hydrogenation (TH) of a variety of alkenes has been achieved with simple AeN''2 catalysts [Ae=Ca, Sr, Ba; N''=N(SiMe3 )2 ] using 1,4-cyclohexadiene (1,4-CHD) as a H source.

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.
