Stereoselectivity in the metathesis reaction of but-2-ene on a β-titanium oxide-supported molybdenum oxide

Abstract

With MoO_x/β-TiO₂ as catalyst the stereo-selective formation of cis- and trans-[²H₄]but-2-ene is observed in the metathesis of equimolar mixtures of cis-[²H₀]- and -[²H₈]but-2-ene, and trans-[²H₀]- and -[²H₈]-but-2-ene, respectively; the yields of cis- and trans-but-2-ene from reactions of the corresponding pent-2-ene isomers are in good agreement, but metathesis of propene selectively yields trans-but-2-ene.
