The thermal reaction of (DMPE)2Ru(naphthyl)H [DMPE = bis(dimethylphosphino)ethane] with isocyanides is described. Thermolysis in the presence of excess neopentyl isocyanide at 60°C in benzene solution results in the formation of the simple substitution complex (DMPE)2Ru(CNCH2CMe3) plus naphthalene. Thermolysis in the presence of excess phenyl isocyanide results in the formation of the unusual monodentate DMPE complex Ru(η2-DMPE)(η1-DMPE)(CNPh)2. Continued heating ultimately forms Ru(DMPE)2(CNPh) plus phenyl isocyanide polymer. Thermolysis with ethyl isocyanide leads to the formation of Ru(DMPE)2(CNEt). Thermolysis in the presence of tert-butyl isocyanide produces two organometallic products, Ru(DMPE)2(CN)2 and Ru(DMPE)2(CN)H, plus four organic products, trimethylacetonitrile, naphthalene, isobutylene, and isobutane, A mechanism is suggested for the formation of these rearrangement and C-N bond cleavage products. The dicyanide molecule Ru(DMPE)2(CN)2 was found to crystallize in the orthorhombic space group Pccn with a = 9.2842 (14) A?, b = 14.1091 (30) A?, c = 16.3641 (50) A?, V = 2143.6 (1.4) A?3, and Z = 4.
