✦ Synopsis

The primary product of flash vacuum pyrolysis of tetraphenylphthalic anhydride at 86OoC/O.O4 Torr is 1,2,3-triphenylbenzopentalene (74%) and not 1,2,3_triphenylbiphenylene, as suggested by Fields and Meyerson (1968) for the product of pyrolysis at 69ooC with long contact time (15-20 sec.).
