Abstract: In independent experiments, four carbons in the 4-pentenal skeleton have been labeled with deuterium or methyl and the fate of each label has been determined as the pentenal was transformed into a cyclopentanone derivative by RhCI (PPh3) 3 (1) at 24-26" c. The catalyst converted 4-hexenal to 2-methylcyclopentanone (2) in CHCI3 and C6H6. Approximately equivalent amounts of hydrocarbon decarbonylation products and RhCI ( ...
