Shedding Light on the Precatalytic Mixture of Pd(OAc)2 and Cooperating Bipyridone Ligands for the C─H Functionalization of Arenes

ChemCatChem, EarlyView.
The reactions of the common palladium precursors Pd(OAc)2 and PdCl2 and cooperating bipyridone ligands leads to well defined complexes which are general precatalysts for the direct C─H arylation of arenes, more active than Pd(OAc)2/ligand mixtures in nonpolar solvents.

Interrelationship of Cuprous Acetylide Cu2C2 Formation and Catalytic Performance in the Reppe Ethynylation of Formaldehyde

ChemCatChem, EarlyView.
Cuprous acetylide, Cu2C2, formed during activation from CuO/Bi2O3/SiO2 pre‐catalysts, has been identified experimentally as the catalytically active phase of the ethynylation of formaldehyde. Direct correlations between catalytic performance and characteristics of Cu2C2 are shown, particularly based on Raman spectroscopy and catalysis for catalysts ...
