Functionalization of edge reconstructed graphene nanoribbons by H and Fe: A density functional study

, 2012
In this paper, we have studied functionalization of 5-7 edge-reconstructed graphene nanoribbons by ab initio density functional calculations. Our studies show that hydrogenation at the reconstructed edges is favorable in contrast to the case of ...

Formal group insertion into aryl C‒N bonds through an aromaticity destruction-reconstruction process

Nature Communications, 2018
Activation of C–N bonds of anilines requires transformation of the amino group into a more reactive functionality. Here, the authors report an aromaticity destruction-reconstruction process that converts abundant anilines into valuable amines through ...
