Diphenyliodonium bis(N-cyanodithiocarbimato)nickel(II) has been prepared and its solid-state thermal autoarylation studied. The diphenyliodonium cation phenylates the complex anion; attack occurs on the two sulfur atoms of the same ligand. This has been verified by the isolation and identification of N-cyanodiphenyldithiocarbimate, (C6H5S)2C=NC=N. As a result of the phenylation the configuration about nickel changes from planar to octahedral, giving a polymeric species.
Iodonium salts of complex anions. III. Isolation and reactions of diphenyliodonium tris(N-cyanodithiocarbimato)cobalt(III)

Isolation and reactions of diphenyliodonium tris(N-cyanodithiocarbimato)cobalt(III), (dpi)3[Co(cdc)3] (I) have been carried out. Pyrolysis reactions of I show that the reactive sites in the anion are the coordinated sulfur atoms of the same ligand. Partial reduction of the metal ion to the bivalent state and liberation of iodobenzene and phenyl disulfide occur simultaneously. In pyridine solution also ligand phenylation occurs; however, arylated ligand decomposes under these reaction conditions. Nonarylated ligand dissociates into thiocyanate and reduction of metal ion to cobalt(II) also occurs in the pyridine reaction. From this solution Co(py)4(NCS)2 has been isolated; this complex has been converted into the corresponding o-phenanthroline and α,α′-dipyridyl complexes. The electronic spectra of the compounds have been recorded.
