  properties of the uncoordinated alkyne in these new rhenium complexes was analyzed, based on 13C NMR data and was compared with reported data on iron complexes. The results obtained indicate that the electronic characteristics of uncoordinated alkynes are similar in both families of complexes. Thus, the different reactivity observed between rhenium and iron complexes is related to the different nature of metallic

  日期：2006.2.1

  Three novel rhodium(I) acetylacetonato (acac) complexes bearing phosphinoalkynes (Ph₂PC≡C-t-Bu, Ph₂PC≡CPPh₂, and Ph₂PC≡CC≡CPPh₂) have been prepared and characterized fully. Addition of B₂cat₃ (cat = 1,2-O₂C₆H₄) to Rh(acac)(Ph₂PC≡C-t-Bu)₂ (1a) led to zwitterionic Rh(η⁶-catBcat)(Ph₂PC≡C-t-Bu)₂ (2a), the first example of this type of compound to contain monodentate phosphine ligands. All new rhodium complexes have been investigated for their ability to catalyse the hydroboration of vinylarenes.Key words: catalysis, hydroboration, phosphinoalkynes, regioselectivity, rhodium.
