title: Fe-catalyzed highly selective ring expansion of alkynylcyclopropyl alkanols to cyclobutanols.
abstract: A Fe-catalytic highly selective ring expansion reaction of alkynylcyclopropyl alkanols to alkynylcyclobutanols via a 1,2-carbon shift under mild conditions was developed. A new class of homogeneous FeCl(2)/O(2) catalytic system was employed in these novel transformations.
