Abstract

original image

Hydrogen abstraction in the spotlight: UV irradiation (365 nm) of dinuclear ruthenium tetrahydride, [(Cp*Ru)(μ-H)4(RuCp*)] (Cp*=η5-C5Me5), in a 2-alkanone, such as acetone or 2-butanone, resulted in the formation of dinuclear oxatrimethylenemethane complexes, [(Cp*Ru)(μ-η31-CH2COCHR)(μ-H)2(RuCp*)] (R=H and CH3), through hydrogen abstraction from the α and α′ positions of the carbonyl group.
