Solvent-free heterogeneous organocatalysis: stereoselective isomerization of α,β-ynones to (E,E)-α,β-γ,δ-dienones catalyzed by polymer-supported tertiaryphosphines

Stereoselective isomerization of α,β-ynones was catalyzed by polymer-supported tertiaryphosphines under solvent-free conditions. (E,E)-α,β-γ,δ-Dienones were obtained with up to 93% isolated yields when JJ-TPP was employed.
