摘要

Flash vacuum pyrolysis of 2-phenylquinoline-3,4-dicarboxylic anhydride at 800°C/0.06 Torr. gave indeno[1,2- ]indole. This was reduced to form 5,10-dihydroindeno[1,2-b]indole and it added nucleophiles to give dihydroindenoindoles with the 10-substituents Ph, NEt 2 , OMe, Me, CH(COOMe) 2 , and CMe 2 NO 2 . ...
