9,9′-Anthril has been synthesized both from 9-anthryllithium/oxalyl chloride at −78 °C, and from methyl 9-anthrilate by a reversebenzilicacid rearrangement. Anthril isomerizes by Diels-Alder reaction. Reduction gives 9,9′-anthroin and hydro-9,9′-anthroin.

Alkyl esters of 9-anthrilic acid isomerize both thermally and photochemically by stereoselective Diels-Alder reaction, while treatment with base induces the shift of 9-anthryl from carbon to oxygen. Photoexcitation of carbon-oxygen-linked bichromophoric anthracenes results in a migratory 9-anthryloxy - 9-anthronyl rearrangement.
