Abstract : The color reactions of several electron acceptors with 48 indoles and related compounds have been studied. The advantages of these complexing spray reagents are that they: (1) are non-destructive (i.e. indoles can usually be regenerated); (2) give an indication of the type of ring substitution (electron-donating or -withdrawing groups); (3) react with 2,3-disubstituted indoles. 2,4,7-Trinitro-9-fluorenone is the generally most useful reagent. These complexing agents are less sensitive and less specific than other chromogenic reagents for indoles. (Author)
