Reductive coupling of perfluoroalkyl- and perfluoroaryl-nitriles with [(eta(5)-C5H5)(2)TiCl](2) provides the corresponding mu-diiminatodititanium complexes. Protonolysis of the Ti-N bonds with ethereal HCl liberates the corresponding perfluoroalkyl- and perfluoroaryl-substituted alpha-dimimes, two of which have been fully characterized by IR, H-1 and C-13 NMR, and X-ray crystallography.
