  The reaction of mu-ethynediyl dipalladium complexes (1) with 2 equiv of phenyl isocyanide in the presence of trialkylphosphines results in the insertion of one molecule of the isocyanide into each of the two Pd-C bonds and produces a new complex Cl(R(3)P)(2)PdC(=NPh)C=CC(=NPh)Pd(PR(3))(2)Cl (3). Complex 3 was characterized by IR and mass, and H-1, C-13, and P-31 NMR spectra. No further insertion of the isocyanide into the Pd-C bonds of 3 was observed. The structure of CI(Et(3)P)(2)PdC(=NPh)C=CC(=NPh)Pd(PEt(3))(2)Cl (3a) has been established by a single-crystal X-ray diffraction analysis. The crystal data are as follows: space group P $$($) over bar 1, a = 32.840(3), b = 11.447(5), c = 9.069(2) Angstrom, alpha = 104.03(2)degrees, beta = 100.02(2)degrees, gamma = 105.76(3)degrees, V = 1202.7(7) Angstrom 3, and Z = 1.
