Abstract: A rapid, transition metal-free, high-yielding, tetrabutylammonium bromide-promoted method of N-arylation is reported within. The optimized conditions tolerated a wide range of secondary amines and was equally effective with bromo- and chlorobenzene-including substituted aryl halides. The… read more here.

Abstract: A one-step strategy is applied to partially quaternize the ligand of UiO-66-NH2, and the resultant UiO-66-N(CH3)3+ showed greatly improved photocatalytic performance for Cr(VI) reduction, with the apparent reaction rate constant k increasing by 8.3 times.… read more here.

DOI: 10.1055/s-0039-1690988
Abstract: An original metal-free regio- and stereoselective intermolecular hydroamination of alkynes is described. Various (E)-enamines were obtained from arylacetylenes and aliphatic secondary amines in the presence of ethylene glycol as a solvent. The latter is assumed… read more here.
