Abstract

[RuCl(CO)₂(Cp)] (1) is obtained in two simple steps from [RuCl₃(H₂O)_x]. [RuCl₂(CO)₃]₂, produced by refluxing [RuCl₃(H₂O)_x] in hydrochloric and formic acids, reacts cleanly with [SiMe₃(C₅H₅)] to give [RuCl(CO)₂(Cp)] (1) in 74% overall yield from [RuCl₃(H₂O)_x]. [OsCl(CO)₂(Cp)] (2) is similarly obtained in four steps from [OsO₄]. Known conversion Of [OsO₄] to [NH₄]₂[OsCl₆], reduction to [OsCl₃] and carbonylation to [OsCl₂(CO)₃]₂ in a tube furnace, and finally reaction with [SiMe₃(C₅H₅)] give [OsCl(CO)₂(Cp)] (2) in 26% overall yield from [OsO₄]. These preparations are a significant improvement over previous published methods, avoiding the intermediacy of [M₃(CO)₁₂].
