254-60-4, Name is 1,8-Diazanaphthalene, belongs to naphthyridine compound, is a common compound. Computed Properties of C8H6N2In an article, once mentioned the new application about 254-60-4.
Reactions of the dinuclear palladium(I) complex [Pd2Cl2(RNC)4] (R = 2,4,6-Me3C6H2) 1 with the N-donor compounds 2,2?-bipyridyl (bipy), 1,10-phenanthroline (phen), and 2,9-dimethyl-1,10-phenanthroline (dmphen) gave dipalladium(I) complexes with chelating N-donor ligands, [Pd2(RNC)2L2] [PF6]2 (L = bipy 2, phen 3 or dmphen 4). The structures of 2 and 4 were characterized by X-ray crystallography. The cation of 2 is composed of two Pd atoms joined by a sigma bond [2.518(3) A] each of which has a square-planar co-ordination involving a terminal isocyanide and a chelating bipy ligand. Complex 3 is expected to have a structure similar to 2 on the basis of spectroscopic data. Complex 4 exhibits a distorted dinuclear structure due to the steric bulk of the N-donor ligand. The Pd-Pd bond length is 2.599(2) A. Each dmphen ligand chelates to a Pd atom and the isocyanide acts as a semibridging ligand. The similar reactions of complex 1 with 2,2?-biquinoline (bquin) and 1,8-naphthyridine (napy) afforded the isocyanide-bridged dipalladium(I) complexes, [Pd2(mu-RNC)2(bquin)2]-[PF6] 2 5 and [Pd2(mu-RNC)2(napy)4][PF6] 2 6, in 24-36% yields. Complex 6 comprises a dinuclear palladium(I) core bridged by two isocyanide ligands [Pd-Pd 2.747(4) A] with four terminal napy ligands co-ordinated in a monodentate fashion.
