摘要

The compound produced by reaction of 3, 4-dibromo-5-nitrotoluene with copper bronze has been shown to be 3, 7-dimethyl-1, 5-dinitrobiphenylene. The analogous 3, 7- dimethoxybiphenylene has been prepared similarly from 3, 4-dibromo-5-nitroanisole. The dipole moment of the dimethyldinitrobiphenylene has been found to be about 2· 4 D. This unexpected result is discussed.
