Extremely high electrophilic metal complexes, composed by a metal cation and very electron poor 蟽-donor ancillary ligands, are expected to be privileged catalysts for oxidation reactions in organic chem. However, their low lifetime prevents any use in catalysis. Here the authors show the synthesis of fluorinated pyridine-Pd2+ coordinate cages within the channels of an anionic tridimensional metal-organic framework (MOF), and their use as efficient metal catalysts for the aerobic oxidation of aliphatic alcs. to carboxylic acids without any additive. Mechanistic studies strongly support that the MOF-stabilized coordination cage with perfluorinated ligands unleashes the full electrophilic potential of Pd2+ to dehydrogenate primary alcs., without any base, and also to activate O2 for the radical oxidation to the aldehyde intermediate. This study opens the door to design catalytic perfluorinated complexes for challenging organic transformations, where an extremely high electrophilic metal site is required. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Safety of 2,3,4,5,6-Perfluoropyridine).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 鈭?8.7 脳 10鈭? cm3路mol鈭?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ路mol鈭? in the liquid phase and 140.4 kJ路mol鈭? in the gas phase. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties. Safety of 2,3,4,5,6-Perfluoropyridine
