Abstract
Oxidation of alcohols is an essential organic
reaction, affording versatile carbonyl groups. To provide a
sustainable solution for environmentally harmful traditional
oxidation methods, the transition-metal catalyzed acceptor-free
dehydrogenation of alcohols has attracted much attention. The
widely used catalysts for the dehydrogenation reaction are
based on precious metals, which are not economical and
environmentally benign. We developed an operationally simple, economical, and environmentally benign acceptorless Fecatalyzed
dehydrogenation of various secondary benzylic alcohols to afford the corresponding ketones and H2. A simple in situ
mixture of readily available Fe(III) acetylacetonate, 1,10-phenanthroline, and K2CO3 was identified as an active catalyst for this
transformation.
