Thioureas as ligands in the Pd-catalyzed intramolecular Pauson-Khand reaction
(Chemical Equation Presented) The thiourea-Pd complex was established as a novel type of catalyst in the PKR of allylpropargylamine, and the demonstrated chemistry may prove to be valuable for developing thiuorea as a ligand for the Pd-catalyzed Pauson-Kh
