Recent Advances in Homogeneous Catalysis with Platinum Group Pincer Complexes: Hydrogen‐Mediated Transformations and Cross‐Coupling Reactions

The Chemical Record, Volume 26, Issue 1, January 10, 2026.
Platinum group pincer complexes are highly efficient catalysts. Additionally, their high activity enables challenging transformations with low catalyst loading. Herein, we summarize the most relevant advances of catalysis involving platinum group pincer complexes. The use of pincer complexes based on platinum group metals is undoubtedly one of the most

Halogen bonding stabilizes a cis-azobenzene derivative in the solid state: A crystallographic study [PDF]

, 2017
Crystals of trans- and cis-isomers of a fluorinated azobenzene derivative have been prepared and characterized by single-crystal X-ray diffraction. The presence of F atoms on the aromatic core of the azobenzene increases the lifetime of the metastable ...
