Controlled regioselective amination of peryleneimides
Perylenediimides (PDIs) and perylenemonoimide diesters (PMIs) can be selectively substituted at the 1,6- or 7,12-positions of the bay region, respectively, by direct amination reactions. The reactions proceed by the formation of a perylene radical anion and its subsequent oxidation, and the yields range from 20-97%. The amination can be tuned to obtain either mono- or disubstituted perylenes by varying the oxidants involved. The presence of the imide cycle is crucial for the transformation, although the amination occurs regioselectively at the bay-region positions distant from the imide cycle.

N-Alkylated and N,N-dialkylated 1,6-diaminoperylene diimides synthesized via copper catalyzed direct aromatic amination
Perylene diimides (PDIs) and naphthalene diimides (NDIs) can be efficiently aminated with primary or secondary amines under mild conditions using Cu(ii) salts as catalysts and air as an oxidant. Depending on the substrate and the amine, yields over 80% ca
