A cobalt-rhodium heterobimetallic nanoparticle-catalyzed reductive cyclization of 2-(2-nitroaryl)acetonitriles to indoles has been achieved. The tandem reaction proceeds without any additives under the mild conditions (1 atm H2 and 25 °C). This procedure could be scaled up to the gram scale. The catalytic system is significantly stable under these reaction conditions and could be reused more than ten times without loss of catalytic activity.
Vicarious Nucleophilic Substitution of Hydrogen in Nitroarenes with α-Substituted Nitriles and Esters. Direct α-Cyanoalkylation and α-Carbalkoxyalkylation of Nitroarenes

Carbanions generated from alkanenitriles bearing α-chloro, α-OR, or α-SR groups and from aliphatic esters bearing α-SR groups react with mononitroarenes to replace hydrogen atoms of the nitroaromatic ring ortho or para to the nitro group with α-cyanoalkyl or α-carbalkoxyalkyl substituents.The nucleophilic replacement of hydrogen with such carbanions proceeds faster than substitution of halogen ortho or para to the nitro group.
