2,3,4,5,6,6-Hexachlorocyclohexa-2,4-dien-1-one
There is also 2,3,4,5,6,6-hexachlorocyclohexa-2,4-dien-1-one around, and actually for sale. Is this the same thing? The diagram here appears to show this as 2,3,4,4,5,6-hexachlorocyclohexa-2,5-dien-1-one Graeme Bartlett (talk) 07:10, 20 November 2021 (UTC)
