Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks
Angewandte Chemie International Edition, EarlyView.A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Novel Expanded Ring N-Heterocyclic Carbenes: Free Carbenes, Silver Complexes, And Structures [PDF]
, 2016 The addition of aromatic formamidines to dihaloalkanes proceeds in air under mildly basic conditions and in polar solvents to afford the corresponding amidinium salts in high yields. To demonstrate the wide scope of this methodology, several five-, six-,

Modulating NHC catalysis with fluorine
Beilstein Journal of Organic Chemistry, 2013 Fluorination often confers a range of advantages in modulating the conformation and reactivity of small molecule organocatalysts. By strategically introducing fluorine substituents, as part of a β-fluoroamine motif, in a triazolium pre-catalyst, it was ...

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
