variety of NN-disubstitutedo-nitroanilines are shown to give benzimidazoleN-oxides, often in high yield, when heated in mineral acid solution. The product is accompanied by small amounts of the denitrated parent compound and p-nitro- and 2,4-dinitro-derivatives. Irradiation of acidic solutions of NN-disubstitutedo-nitroanilines similarly yields either the corresponding benzimidazoleN-oxide or the benzimidazole

1‐naphthylamine N‐oxides with diazo compounds was developed to afford various biologically important 1H‐benzo[g]indolines. This coupling reaction proceeds undermild reaction conditions and does not require external oxidants. The only by‐products are dinitrogen and water. More significantly, this reaction represents the first example of dual functiaonalization of unactivated a primary C(sp3)Hbond and C(sp2)H

Double role: A traceless directinggroup also acts as an internal oxidant in a novel RhIII‐catalyzed protocol developed for the synthesis of ortho‐alkenylated tertiary anilines (see scheme). A five‐membered cyclometalated RhIII complex is proposed as a plausible intermediate and confirmed by X‐ray crystallographic analysis.
