The N-arylation of diketopyrrolopyrroles with aryl fluorides free of nitro groups was successfully achieved for the first time. Diketopyrrolopyrroles possessing 3,4-dimethoxyphenyl and benzofuryl substituents underwent reaction with, for example, pentafluoropyridine, in the presence of K2CO3 in N-methyl-2-pyrrolidone to give the desired products in moderate yields. Their photophys. properties in solution were found not to differ significantly from those of analogous N-alkylated diketopyrrolopyrroles, whereas in contrast to the latter compounds, they were found to possess fluorescence in the solid state. The photophys. properties of all compounds were rationalized by using time-dependent d. functional theory. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3SDS of cas: 700-16-3).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C鈥揌 in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.SDS of cas: 700-16-3
