Phosphine ligand-free bimetallic nanoparticles (NPs) composed of Ni(0)Pd(0) catalyze highly selective 1,4-reductions of enones, enamides, enenitriles, and ketoamides under aqueous micellar conditions. A minimal amount of Pd (Ni/Pd = 25:1) is needed t

The cinchona thiourea moiety in the self-assembled modularly designed organocatalysts (MDOs) switches off the iminium catalysis of these catalysts. In this study, it was found that the inhibited iminium catalysis could be switched on by using an appr

Highly selective direct monofluorination of indoles and arenes was developed through an approach that allows site-specific solubility of substrate and fluorine source in the micelle. This approach was highly selective for a broad range of substrates
