The use of a new amino acid reagent 1,8-diazafluoren-9-one (DFO), which produces a highly fluorescent species with latent fingerprints on paper, is described. Spectral characteristics of the fluorescent fingerprint show excitation (λex approximately

Glycine, valine, and α-amino acid esters react with (1,3-dioxoindan-2-ylidene)malononitrile (1) by a Michael addition–elimination mechanism with replacement of one cyano group by the α-amino acid or α-amino acid ester entity. These adducts under

The ninhydrin reaction is shown to involve stereospecifically formed azomethine ylides of two types by trapping of the intermediates with maleimides as dipolarophiles. One type of azomethine ylide, in which the carboxyl group of theoriginal ∝-amino

Trapping experiments with dipolarophiles provide evidence for the formation of 1,3-dipoles as interemediates in the ninhydrin reaction and protonated Ruhemann's purple is shown to be a stable N-protonated 1,3-dipole by trapping experiments and by an
