A platinum upgrade: Zeise's dimer [{Cl2Pt(CH2CH 2)}2] catalyzes the activation of linear propargylic alcohols and esters. Depending on the presence of a suitably placed alcohol group proximal or distal to the propargylic center, a cyclo-reorganization occurs that delivers either valuable β-keto tetrahydropyrans (from propargylic alcohols), or cyclic dienolethers (from propargylic esters).
