The 2,1‐benzazaarsole ( 1 ) showed a diene‐like reactivity towards selected alkynes RC≡CR (R=CO 2 Me, C 5 F 4 N) thus forming 1‐arsa‐1,4‐dihydro‐iminonaphthalenes 2 a and 3 a as hardly isolable intermediates, that underwent facile CH→NH proton migration leading to before elusive substituted 1‐arsanaphthalenes 2 b and 3 b that could be completely structurally characterized.
