1,2-Dimethoxybiphenylene reacted with dichlorocarbene to give three chloro(methoxy)-6<I>H</I>-benzo[3,4]cyclobuta[1,2]cyclohepten-6-one derivatives, two chloro(methoxy)fluorenones and two dimethoxyfluorenones. The reaction with dibromocarbene gave similar products. The formation of these products serves as unequivocal chemical evidence for bond fixation of 1,2-dimethoxybiphenylene. The chloro(methoxy)-6<I>H</I>-benzo[3,4]cyclobuta-[1,2]cyclohepten-6-one was led to 9-chloro-5-hydroxy-6<I>H</I>-benzo[3,4]cyclobuta[1,2]cyclohepten-6-one, the first tropolone analogue of biphenylene. This compound was shown to exist in only one of the two possible tautomers in contrast with general monocyclic tropolones.
