A small molecule, namely nitroacenaphthene, is reported for the first time as a recyclable visible-light photocatalyst for the construction of the C=N bond from sulfonyl azides and amines. This scalable, site-selective protocol provides a convenient way to access various sulfonyl amidines under mild conditions. Two reaction pathways are proposed, according to different transformation patterns.

The amidation reactions of 8-methylquinolines with azides catalyzed by a cationic rhodium(III) complex proceed efficiently to give quinolin-8- ylmethanamine derivatives in good yields via C(sp3)-H bond activation under external oxidant-free conditions. A catalytically competent five-membered rhodacycle has been isolated and characterized, revealing a key intermediate in the catalytic cycle.

Imidazole-1-sulfonyl azide hydrogen sulfate is presented as an efficient reagent for the synthesis of sulfonyl azides from primary sulfonamides. The described method is experimentally simple and high-yielding and does not require the addition of Cu salts. Furthermore, 15N NMR mechanistic studies show the reaction proceeds via a diazo transfer mechanism. Imidazole-1-sulfonyl azide hydrogen sulfate provides a considerable advantage over existing diazo transfer reagents in terms of impact stability, cost, and ease of use.
