General Description

6-Heptenoic acid is a straight-chain terminal alkenoic acid. Electrochemical oxidation of 6-heptenoic acid adsorbed on Pt(111) electrode surface has been reported. Preparation of 6-heptenoic acid has been reported.

Synthesis

synthesis of 6-Heptenoic acid and higher homologs of this ω-unsaturated acid, a study of the pyrolysis of wheptano lactone was undertaken. The lactone was prepared by the oxidation of cycloheptanone under Baeyer-Villiger conditions. The pyrolysis of ω-unsaturated acid was effected by dropping the substance under a nitrogen atmosphere into a heated column packed with glass beads.
