Compared with the ripeness of olefin metathesis, exploration of the construction of carbon–carbon double bonds through the catalytic carbonyl–olefin metathesis reaction remains stagnant and has received scant attention. Herein, a highly efficient AuCl3-catalyzed intramolecular ring-closing carbonyl–olefin metathesis reaction is described. This method features easily accessible starting materials, simple operation, good functional-group tolerance and short reaction times, and provides the target cyclopentenes, polycycles, benzocarbocycles, and N-heterocycle derivatives in good to excellent yields.
Refined Insight in Stereochemical and Directional Features of the Fe1-Mediated Dehydrogenation of Tetralin

Experimental results demonstrate that, in the course of gas-phase Fe+-mediated dehydrogenation of tetralin, the metal ion sticks to the same plane of the hydrocarbon surface.The study if 5-substituted, labeled tetralin analogues reveal the operation of an interesting substituent effect: Steric hindrance imposed by a CH3 group at C(5) deflects the metal tothe more easily accessible region of C(1)/C(2); in contrast, a CH3O substituent at C(5) directs the metal ion to the more congested C(3)/C(4) region which clearly points to a coordination of Fe+ to the MeO group in the course of the haptotropic migration.
