Synthesis and thermal reaction of 2‐perfluoropropyl or (2‐pyridyl)‐5‐phenyl‐6‐[4‐(4‐ethynylphenoxy) phenyl] ‐as‐triazine

Abstract
4‐(4‐Ethynylphenoxy) benzil was separately reacted with two amidrazones to provide acetylene‐containing phenyl‐as‐triazine products. Each product consisted of two isomers which were separated by high pressure liquid chromatography and analyzed by mass spectroscopy. Differential scanning calorimetry was employed to study the thermal reaction of the acetylene‐containing phenyl‐as‐triazine products. The principal component from the thermally induced reaction of the acetylene‐containing phenyl‐as‐triazine was identified by mass spectroscopy as a dimer.
