摘要

Difluoroethyne, FCCF 1, has been prepared by vacuum pyrolysis of perfluoro-1, 2, 3-triazine, isolated in pure form and characterized by 19F NMR and gas phase IR spectroscopy; its decomposition, with a half-life-time at 300 K and ca. 2.5 mbar of ca. 15 min, yields in the first step a polymer and: CF2, the latter either oligomerizing or reacting with 1 to form three different C3F4 isomers.
