  Synthesis and structure of 1,3-dienolate (CH2C(O)CHCH2) complex of dipalladium(I) moiety: contribution of π-olefin co-ordination of enolate to transition metal

  摘要：

  1,3-Dienolate dipalladium(I) complex [{mu-CH2C(O)CH=CH2}Pd-2(PPh3)(2)(mu-Cl)] (2) is prepared and characterized. Complex 2 is easily protonated to yield 2-hydroxy-1,3-butadiene dipalladium(I) complex [{(mu-eta(2):eta(2)-CH2=C(OH)CH=CH2}Pd-2(PPh3)(2)(mu-Cl)][BF4] (3). On the basis of the comparative analyses on IR and NMR spectra and X-ray structure analysis, the co-ordination mode of 1,3-dienolate on Pd-Pd is revealed to involve the resonance between C-bound and pi-olefin-bound enolate structures.
