30 May 1980TL;DR: In this article, the present invention is concerned with novel xanthene compounds of the formula "STR1" wherein each R 1 the same or different is hydrogen or alkyl, each R 2 the same OR different is alkyL or phenyl, R 3 is phenyl or alkaline, Y is an electron-withdrawing group and A is an anion.
Abstract: In one embodiment, the present invention is concerned with novel xanthene compounds of the formula ##STR1## wherein each R 1 the same or different is hydrogen or alkyl, each R 2 the same or different is alkyl or phenyl, R 3 is phenyl or alkyl, Y is an electron-withdrawing group and A is an anion. In another embodiment, the present invention is concerned with photographic products and processes employing these xanthene compounds.

TL;DR: In this article, the reduction of anthraquinone and 9 : 10-diacetoxy-anthracene to Xanthydrol and xanthene by controlled potential electrolysis on a mercury cathode in dimethylformamide, phenol being present as proton donor in the experiment.
Abstract: WE have examined the reduction of anthraquinone and 9 : 10-diacetoxy-anthracene to 9 : 10-dihydro-anthracene and xanthydrol to xanthene by controlled potential electrolysis on a mercury cathode in dimethylformamide, phenol being present as proton donor in the experiment on the quinone. We have not previously encountered a report of carbon-oxygen scission brought about by such means.
