para-Formylation of nitroarenes via vicarious nucleophilic substitution of hydrogen with tris(benzotriazol-1-yl)methane

Add time:08/28/2019    Source:sciencedirect.com

Reaction of nitroarenes 1 with tris(benzotriazol-1-yl)methyl 2 anion afforded para-bis(benzotriazol-1-yl)methylated products 3 which, upon treatment with zinc bromide and hydrochloric acid, yielded the corresponding p-nitroarylaldehydes 4 in good yields.
