Palladium-catalysed transformation of readily available mixed carbonates 1a–l gives rise to a variety of allenicpolyunsaturated aldehydes and ketones 2a–l. These carbonyls were sometimes contaminated with minor amounts of the undesired acetylenic regioisomers 3, and could be purified by silicagel chromatography.
