Reactions of benzonitrile with diiodides of neodymium, dysprosium, and thulium

The reactions of LnI2 (Ln = Nd, Dy, Tm) with benzonitrile are accompanied by disproportionation, resulting in the formation of triiodides LnI3(PhCN)4 and an intractable mixture of monoiodine derivatives LnI(R)R". Hydrolysis of the mixture gives 2,4,6-triphenyl-1,3, 5-tiazine, 2,3,5,6-thetraphenyl-1,4-pyrazine, and 2,4,5-triphenylimidazole. The reaction of dysprosium diiodide with acrylonitrile gives a metal-containing polymer with a molecular weight of 2700. Treatment of the polymer with water results in separation of DyI2(OH)(H2O)x to give metal-free polyacrylonitrile with a molecular weight of 2400.
