Abstract

Flash vapor pyrolysis of 1,6,11-dodecatriyne at 500 to 600 °C and 0.01 torr affords 1,2,3,6,7,8-Hexahydro-[as]-indacene and dehydro derivatives. An uncatalyzed and highly exothermic two-step cycloaromatization mechanism is suggested. This proceeds through initial formation of a 1,4-diradical.
