title: CoBr2-TMTU-zinc catalysed-Pauson-Khand reaction.
abstract: A cobalt-TMTU complex, derived from the in situ reduction of CoBr(2) with Zn in the presence of TMTU, can catalyze Pauson-Khand reaction at a balloon pressure of CO, which enables the synthesis of structurally diverse cyclopentenones. This catalytic system works efficiently for both intermolecular and intramolecular PK reactions.
