Synthetic strategies for 5- and 6-membered ring azaheterocycles facilitated by iminyl radicals [PDF]
, 2016 The author thanks EaStCHEM for financial support.The totality of chemical space is so immense that only a small fraction can ever be explored. Computational searching has indicated that bioactivity is associated with a comparatively small number of ring ...

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates
ChemCatChem, EarlyView.The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Polycyclic Aromatics as Promising Phosphorescence Materials
ChemistryEurope, EarlyView.This review focuses on the recent progress of polycyclic aromatic compounds (PACs)‐based phosphorescent materials. Their molecular structural characteristics as promising phosphors are highlighted, and the efficient strategies from molecular and aggregation levels have been illustrated systematically to promote the development of PACs with desirable ...
