Decamercuration of Ruthenocene

The reaction of [Cp2Ru] with Hg(OAc)2 in dichloroethane under reflux affords the complex 1 in 88% yield. The corresponding decahalo-substituted complexes (Cl, Br, I) can be prepared readily from 1 by reaction with CuCl2, KBr3, and KI3 (from KX and X2), respectively.

Crystal structure of osmocene, Os(?-C5H5)2

Crystals of osmocene, Os(η-C5H5)2, are orthohombic:Pnma,M r =321.3,a=7.079(2),b=8.908(1),c=12.771(2),V c =806 A3,Z=4,D x =2.640 g cm−3, MoKα (λ=0.71069 A),μ=151 cm−1,F(000)=584,T=293 K,R=0.04 for 730 observed reflections. Osmocene is isomorphous with ruthenocene and the molecules have averageD 5h symmetry with a mean Os-C distance of 2.19(1) A (compared with 2.186 A forRu-C).

Photochemical Ethoxycarbonylation, Formylation, and Ethoxymethylation of Ruthenocene in Ruthenocene–Polychloromethane–Ethanol Systems

Abstract Similar to ferrocene the UV-irradiation of ruthenocene–polychloromethane–ethanol systems brings about substitution (ethoxycarbonylation for CCl4, formylation for CHCl3, and ethoxymethylation for CH2Cl2) and oxidation. When CHCl3 and CH2Cl2 are used, substitution is dominant. In the irradiation of ruthenocene–CCl4–ethanol system, [Ru(C5H5)2]+[RuCl4]− and cyclopentenes substituted by chlorine and trichloromethyl are obtained. The excitation of the CT-complex between ruthenocene and polychloromethane initiates the reaction.
