Branching out: The cationic ruthenium–hydride complex [Ru]+ was found to be a highly effective catalyst precursor for the conjugate addition of unactivated olefins to α,β‐unsaturated carbonyl compounds to yield tetrasubstituted olefins. A kinetic analysis provides support for the mechanism involving a regioselective olefin insertion and rapid alkene isomerization steps.
