Abstract
2-Haloaryl aldehydes and ketones react with allene (1 atm) in the presence of 2 mol% of a non-phosphine cyclopalladated catalyst to afford cyclopenten ols and cyclohexenols via nucleophilic cyclisation of intermediate pi-allyl palladium species. A possible mechanism for this unusual reactivity is sugg ested.
