2-Haloaryl aldehydes and ketones react with allene (1 atm) in the presence of 2 mol% of a non-phosphine cyclopalladated catalyst to afford cyclopentenols and cyclohexenols via nucleophilic cyclisation of intermediate π-allylpalladium species. A possible mechanism for this unusual reactivity is suggested.
