High‐performance tetrahedral palladium nanocatalyst for microwave‐assisted organic synthesis

Bulletin of the Korean Chemical Society, EarlyView.
Tetrahedral palladium nanoparticles anchored on graphene sheets (T‐Pd/graphene) were synthesized through a solvent‐free process involving thermal decomposition in an environment rich in carbon monoxide at elevated temperatures and have high catalytic activity for organic chemistry reactions. Abstract Palladium is widely recognized for its effectiveness

Base-Promoted Ammonia Borane Hydrogen-Release [PDF]

Journal of the American Chemical Society, 2009
The strong non-nucleophilic base bis(dimethylamino)naphthalene (Proton Sponge, PS) has been found to promote the rate and extent of H(2)-release from ammonia borane (AB) either in the solid state or in ionic-liquid and tetraglyme solutions. For example, AB reactions in 1-butyl-3-methylimidazolium chloride (bmimCl) containing 5.3 mol % PS released 2 ...

Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

Chemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

Chemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...
