The solvolysis of N-acetoxy-2-acetylaminofluorene in aqueous acetone at neutral pH proceeds exclusively with nitreniumion formation while under the same conditions, the 4-aminobiphenyl analogue exclusive acyl–oxygen scission.

An approach to indole derivatives fromN-arylhydroxamicacids and malononitrile via a [3,3]-sigmatropic rearrangement and intramolecular cyclization is described. Reactions of N-arylhydroxamicacids 1a-c, 2a-c and 3a-c with malononitrile in the presence of triethylamine at room temperature gave the corresponding α-cyanoacetamide derivatives 4a-c, 5a-c, 6a-c, 7a-c and 8a-c. Thermal treatment of 4a-c

Upon solvolysis in neutral 40% aqueous acetone, N-acetoxy-1-N- and N-acetoxy-2-N-acetylaminonaphthalene exhibit completely different modes of reaction; the former reacts with nitrenium ion formation, while the latter undergoes acyl oxygen scission.
