An apparent similarity between the mass spectral and thermal reactions of trans-pentafluorocinnamic acid. Synthesis of 5,6,7,8-tetrafluorocoumarin
Abstract
The pyrolysis of trans-pentafluorocinnamic acid at 400° or the photolysis of sodium pentafluorocinnamate at 100° afford 5,6,7,8-tetrafluorocoumarin.
