Notes:
Formation of 2-Pyrones from 5-Halogen-substituted (Z)-2,4-Pentadienoic Acids and their Alkyl EstersThe thermolysis of the isomeric tetrachloro-phenyl-pentadienoic acids 1a, 4a und the corresponding esters lb, 4b yields the same 2-pyrone 2. This fact is explained by 1,5-chlorine shift within a ketene intermediate.
