  3,5-Bis(diphenylphosphinoethyl)pyrazolate ligand (PNNPC2) and its dirhodium complexes: Comparison with related quadridentate dinucleating diphenylphosphinomethyl (PNNPPy) and phthalazine derivatives (PNNPPh)

  摘要：

  Dirhodium carbonyl complex with the 3,5-bis(diphenylphosphinoethyl) pyrazolato ligand (PNNPC2), [(mu-kappa(2): kappa(2)-PNNPC2) Rh-2(CO)(3)]BF4, is prepared and its reactivity is studied as compared with the previously reported 3,5-bis(diphenylphosphinomethyl)pyrazolate (PNNP), [(mu-kappa(2): kappa(2)-PNNP){Rh(CO)(2)}(2)]BF4, and 1,4-bis( diphenylphosphinomethyl) phthalazine (PNNPPh) derivatives, [(mu-kappa(2): kappa(2)-PNNPPh){Rh(CO)(2)}(2)](BF4)(2). The three quadridentate ligands are different in the size of the central ring and the charge; six-membered ring/neutral (PNNPC2) vs. five-membered ring/mono-negative (PNNP) vs. six-membered ring/neutral (PNNPPh). The number of the carbonyl ligands (n) in the dirhodium carbonyl complexes, [(mu-PNNP) Rh-2(CO)(n)](BF4)(x), is dependent on the dinucleating ligand: n = 2 (PNNPPh), 3 (PNNPC2) and 4 (PNNPPy). The three dirhodium carbonyl complexes serve as 4e-acceptors, and their reactivities turn out to be very similar as can be seen from formation of the analogous, unique tetranuclear l4-acetylide ([(mu-PNNP)(2){Rh(CO)}(4)(mu(4)-C C-R)](BF4)(x)) and mu(4)-dicarbide complexes ([(mu-PNNP)(2){Rh(CO)}(4)(mu(4)-C-2)](BF4)(x)).
