Four mono(arylhydrazone)s of benzocyclobutene-1,2-dione (BBD) have been prepared in which the aryl group is 2,4-dinitrophenyl, 4-bromophenyl, phenyl, and 4-nitrophenyl. The first three have been separated into their E- and Z-isomers whose configurations are assigned on the basis of spectra and Rf values. Improvements in the preparation of BBD from 1,2-dibromo-1,2-dihydrobenzocyclobutene are described
已经制备了苯并环丁烯-1,2-二酮 (BBD) 的四种单(芳基腙),其中芳基是 2,4-二硝基苯基、4-溴苯基、苯基和 4-硝基苯基。前三个已被分离为它们的 E 和 Z 异构体,其构型是根据光谱和 Rf 值分配的。描述了从 1,2-二溴-1,2-二氢苯并环丁烯制备 BBD 的改进。
