Intramolecular nucleophilic substitutions of co-ordinated aryl halides. A preparation of chromans
Abstract
3-(o-Fluorophenyl)propan-1-ol can be cyclised readily to chroman either through chromium tricarbonyl complexes or (as also with substituted fluorophenylpropanols) by the action of the (η6-benzene)(η5-ethyltetramethylcyclopentadienyl)rhodium(III) cation.
