Ruthenium hydrides promote the positional isomerization of 1,3-dienes into more highly substituted 1,3-dienes in a stereoconvergent manner. The reaction can also be conducted in one pot starting with an ene-yne metathesis of terminal alkynes and alkenes and a subsequent decomposition of the Grubbs catalyst into a ruthenium hydride, which promotes the dienyl isomerization.
