1997) first synthesized indanediones as intermediates for preparing substituted ninhydrins for use as a fingerprint reagent.
Working Solution 2g 1,2 - indanedione 70ml ethyl acetate 930ml HFE 7100 Two grams of IND were dissolved in 70ml of ethyl acetate, and 930ml HFE 7100 were added to make a final volume of one liter.
The class of chemicals this American team ultimately fingered, known as indanediones, recently received a U.S.
Indanediones appear to fit the bill better than any of the various fingerprinting compounds now available.
The indanediones developed by Joullie can be produced for a fraction of that cost via a relatively straightforward, reliable sequence of reactions.
Other interests include rearrangements of phthalides to indanediones
, and hydrolysis of metal ion complexes of biacetylacetone-ethylenediamine analogues.
