标题:Process for preparing 3-(indol-3-yl)-dehydronaphthalide hydrochlorides
发明人：CHIANG YUNN H
权利人:POLAROID CORP
摘要: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.
