Buchwald electronic materials

Figure 2.8 Some components for electronic materials, which use the Buchwald-Hartwig reaction as a key step developed by Merck Gmbh [41].

Both Buchwald and Hartwig have explored the use of palladium-catalyzed amination for the synthesis of dendrimers and polyanilines. Dendrimers, such as 48, can be easily assembled through sequential aiylation of aminoanilines.89 These dendrimers are useful in creating metal-organic frameworks and often can exhibit interesting electronic effects, such as diradicals, and as optical materials. Polymeric anilines 49 are of intense interest due to their unique electrical conducting properties. Using the...
