containing various N‐heterocycliccarbene (NHC) ligands have been successfully synthesized by the reaction with various β‐diketonate complexes. Treatments of Pd(acac)2 with NHC salts such as 1,3‐di(2,6‐diisopropylphenyl)imidazolium chloride (IPr·HCl) or 1,3‐di(mesityl)imidazolium chloride (IMes·HCl) resulted in [Pd(acac)(NHC)Cl] complexes and these complexes were characterized by NMR. Moreover, these

catalyzed reactions and probes the separation of a number of readily available palladium complexes from reaction mixtures with highly stable ceramic membranes. A number of different processing methods, namely, online, at-line, and off-line are compared and contrasted. A high rejection of Palladium species and consequently very low palladium contamination of reactionproducts with a single organic solvent

Alternative procedures are reported for the preparation of PEPPSI-type palladiumcomplexes (PEPPSI = pyridine-enhanced precatalyst preparation stabilization and initiation) in good to excellent yields. One method involves the reaction of [(NHC)Pd(acac)Cl] complexes (NHC = N-heterocyclic carbene, acac = acetylacetonate) with hydrohalides (HX; X = Cl, Br, I) of pyridine or 2,6-lutidine. Two other one-pot
