Bis-indolyl phthalides and naphthalides

This invention relates to indole phthalein indicator dyes including phthalides and naphthalides wherein one of the indol-3-yl radicals is substituted with a hydrogen-bonding group on a carbon atom adjacent to the nitrogen atom of the indole ring. In a preferred embodiment, one of the indol-3-yl radicals is substituted with a hydrogen-bonding group and the other indol-3-yl radical is substituted with a hydrogen-bonding group or with an electron-withdrawing group. These indicator dyes, especially those of the preferred embodiment, possess a relatively high pKa and a relatively broad absorption spectrum in the visible range.

3-(Indol-3-yl)dehydronaphthalide hydrochlorides

This invention is concerned with a novel class of protonated compounds, namely, 3-(indol-3-yl)dehydronaphthalide hydrochlorides, with their synthesis by the reaction of a 3-(indol-3-yl)naphthalide and a high-potential quinone in an inert anhydrous aprotic solvent in the presence of a carboxylic acid catalyst, and with the synthesis of indole naphthalide indicator dyes by reacting the said dehydronaphthalide hydrochlorides and an indole in an aromatic hydrocarbon solvent in the presence of a carboxylic acid catalyst.
