  Studies on the use of bidentate ligands in the directed Pauson-Khand reaction

  摘要：

  The use of bidentate ligands in the directed Pauson-Khand reaction was investigated. Substrates with a three-carbon linkage between the two heteroatoms gave better results than substrates containing two-carbon tethers. Higher yields and better regioselectivities were observed with thioamines and bisthioethers compared to diamines. Overall, only a few bidentate substrates showed marked improvements over previous results obtained with analogous monodentate compounds. Rationalizations based on the possible modes of cycloaddition operative for the various substrates studied are presented.
