catalytic tandem process involving a ring-closing carbonyl-olefin metathesis and a transfer hydrogenation are described. 1,4-Cyclohexadiene has been used as an H2 surrogate to reduce the cyclic alkenes formed after the metathesis step. The same cationic gallium(III) complex, [IPr·GaCl2][SbF6], performs the two steps with functional group tolerance. This stereoselective reaction leads to 1,2-cis-disubstituted
