Not a diphenylketene dimer , as has long been presumed, but the p ‐quinodimethane derivative 1 is formed (inter alia) upon pyrolysis of benzilic acid. In contrast to the related orange‐yellow 2 (“ Thiele 's hydrocarbon”), 1 is deep black‐red; this can be attributed to expansion of the conjugated system by the condensed furanone ring.
