Development of well-defined multivalent systems with densely packed multiple functional groups located within a single mol. structure provides an excellent opportunity to generate catalysts of enhanced activity. A series of mono-, di- and trinuclear Pd(II) complexes based on polyketonate ligands allied with 2,2′-bipyridine was designed, synthesized and fully characterized in both solution and solid state. The mono-, di- and tritopic β-diketonate mols. serve as scaffolds for Pd(II) active sites which, in the two latter cases, are forced into close proximity. Application of the complexes as catalysts in Suzuki-Miyaura cross-coupling as a model reaction revealed significant differences in reaction yields and a trend in reactivity reflecting their nuclearity. In the experimental materials used by the author, we found 2,5-Dibromopyridine(cas: 624-28-2Application of 624-28-2)
2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Application of 624-28-2
