Cyclic Alkenes

We report a catalytic tandem process involving a ring-closing carbonyl-olefin metathesis and a transfer hydrogenation. 1,4-Cyclohexadiene has been used as H<sub>2 </sub>surrogate to reduce the cyclic alkenes formed after the metathesis step. The same NHC-stabilized cationic gallium(III) complex, [IPr<b><sub>˙</sub></b>GaCl<sub>2</sub>][SbF<sub>6</sub>], performs the two steps with functional group tolerance. This reaction is stereoselective, leading either to 1,2-<i>cis</i>disubstituted cyclopentanes or to a variety of cyclohexanes. DFT computations support an unexpected mechanism involving the activation of 1,4-cyclohexadiene by superelectrophilic gallium(III) dimers.
