A series of bicyclic alkylamino carbenes (BICAAC) ({where|exactly where} N-aryl = dipp, mes, {2|two},6-dimethyl-4-(dimethylamino)phenyl, 5a-d) and their novel air- and moisture-resistant pyridine (pyridine, {4|four} dimethylaminopyridine) containing palladium PEPPSI-type Pd(II) complexes (6a-e) {were|had been|have been} synthetized and characterized. The new palladium complexes have shown {high|higher} activity in Mizoroki–Heck coupling reaction even at as low as {100|one hundred} ppm loading (TON {up to|as much as} 10000). Kinetic {studies|research} revealed that reactions carried out {in the|within the|inside the} presence of elemental mercury resulted in {decrease|reduce|lower} in activity. It indicates that the coupling reaction {may have|might have} {both|each} molecular and Pd(0)-mediated catalytic paths. n-(2-Methoxyethyl)aniline supplier 22112-84-1 Data Sheet PMID:34816786
