A room-temperature-stable electride and its reactivity: Reductive benzene/pyridine couplings and solvent-free Birch reductions

Nathan Davison et al.

Summary: In this work, a room-temperature-stable electride reagent was successfully synthesized via mechanochemical ball milling using easily accessible starting materials. Experimental and computational studies confirmed the presence of anionic electrons in the amorphous product, thus defining it as an electride. This electride reagent demonstrated versatile reactivity, including mediation of C-H activation, C-C coupling, and solvent-free Birch reduction, introducing it as a versatile reagent for the synthetic chemistry community.

Nickel-Catalyzed Intramolecular Alkene Difunctionalization by Ball-Milling

Matthew T. J. Williams et al.

Summary: A mechanochemical nickel-catalyzed intramolecular difunctionalization reaction of alkene tethered aryl halides with alkyl halides is developed for the synthesis of 3,3-disubstituted heterocycles, namely oxindoles, with shorter reaction times compared to solution-phase methods. The process is solvent minimized by employing liquid-assisted grinding (LAG) quantities of DMA and avoids the need for chemical activation of the terminal reductant (manganese) through mechanical grinding. The reaction can be scaled up to yield gram quantities of product and modest enantioinduction is possible with a chiral PyrOx ligand.

Mechanochemical Approach for Air-Tolerant and Extremely Fast Lithium-Based Birch Reductions in Minutes

Yunpeng Gao et al.

Summary: Birch reduction is a powerful method to dearomatize arenes, but traditional liquid ammonia-based method has drawbacks. We report an ammonia-free lithium-based Birch reduction using ball-milling technique, which is characterized by its simplicity, short reaction time, broad substrate scope, and no requirement for dry bulk solvents. The method shows potential in reducing bioactive target molecules and gram-scale synthesis.

Nathan Davison et al.

Summary: This study comprehensively investigated the coordination chemistry of a hexa-dentate neutral amine ligand and group-1 metal cations. Various coordination modes were observed depending on the metal ionic radii and metal's substituent. The results of this study provide guidance for future applications of these ligands in pursuing highly reactive and elusive s-block and rare-earth metal complexes.

Metals Production and Metal Oxides Reduction Using Hydrogen: A Review

A. Rukini et al.

Summary: Hydrogen is considered as a clean fuel energy source and a reducing agent for metals production. However, its common use in metals production is still limited. Laboratory studies on hydrogen reduction of metal oxides have provided fundamental knowledge for industrial metals production processes. Recently, there has been further development in experimental approaches, applications, and technologies related to hydrogen reduction of metal oxides. Hydrogen has the potential to recover valuable metals from secondary resources and has applications beyond extractive metallurgy.

The Direct Mechanocatalytic Suzuki-Miyaura Reaction of Small Organic Molecules

Wilm Pickhardt et al.

Summary: This study achieved the molecular Suzuki cross-coupling reaction mechanochemically, without solvents, ligands, or catalyst powders. By using a catalytically active palladium milling ball, products were formed in quantitative yield in as little as 30 min. The adjustment of milling parameters eliminated abrasion from the catalyst ball and allowed for systematic catalyst analysis for the first time.

Mechanochemically Generated Calcium-Based Heavy Grignard Reagents and Their Application to Carbon-Carbon Bond-Forming Reactions

Pan Gao et al.

Summary: The use of calcium-based heavy Grignard reagents (R-CaX) in organic synthesis is not well-explored compared to conventional magnesium-based Grignard reagents (R-MgX). This is mainly due to the lack of a simple method to access organocalcium nucleophiles from readily available starting materials. In this study, the researchers demonstrate a mechanochemical technique using ball milling to generate calcium-based heavy Grignard reagents without complicated pre-activation processes. The method allows for the development of novel cross-electrophile-coupling reactions mediated by arylcalcium nucleophiles, which is difficult using conventional Grignard reagents.

From Inert to Catalytically Active Milling Media: Galvanostatic Coating for Direct Mechanocatalysis

Maximilian Wohlgemuth et al.

Summary: The inert milling balls coated with Pd were used as catalyst in the direct mechanocatalytic Suzuki reaction, achieving high yields (>80%) and recycling capabilities. The coating sequence, support material, and layer thickness were optimized for catalyst retention, abrasion resistance, and conversion. The approach was also applied to coating milling vessels, revealing the interplay between catalytically available surface area and mechanical energy impact in mechanocatalysis.

Robust Cobalt Catalyst for Nitrile/Alkyne [2+2+2] Cycloaddition: Synthesis of Polyarylpyridines and Their Mechanochemical Cyclodehydrogenation to Nitrogen-Containing Polyaromatics**

Chang-Sheng Wang et al.

Summary: The study presents a simple and inexpensive catalytic system based on cobalt(II) iodide, 1,3-bis(diphenylphosphino)propane, and Zn for the [2+2+2] cycloaddition of various nitriles and diarylacetylenes to synthesize a broad range of polyarylated pyridines. DFT studies support a reaction pathway involving oxidative coupling of two alkynes, insertion of the nitrile into a cobaltacyclopentadiene, and C-N reductive elimination, leading to the synthesis of tetra- and pentaarylpyridines that can be used as precursors for nitrogen-containing polycyclic aromatic hydrocarbons.
