Rhodium(III)-mediated cycloaddition of alkynes: reactivity of [Cp*Rh(η2-NO3)(OTf)] bearing two labile ligands
摘要:
[Cp*Rh(eta(2)-NO3)(OTf)] (1) mediated cyclodimerization or cyclotrimerization of alkynes and alkynyl esters. In addition, compound I reacted with propargyl halides to give triply halide-bridged dinuclear compounds, [Cp*Rh(mu(2)-X)(3)RhCp*](OTf) (X = Cl or Br). (C) 2003 Elsevier B.V. All rights reserved.
