Abstract

Both H2 and O2 are coordinated to the coordinatively unsaturated comples 1 without bond breaking. While 1·H2 is only stable in a hydrogen atmosphere, 1·O2 does not split off oxygen even under high vacuum. At 60°C in solvents such as benzene, 1,2-dichloroethane and 2-propanol 1·H2 catalyzes the reductions of alkenes and -unsaturated ketones: thus for example benzylidene-acetone in 2-propanol gives benzylacetone and 4-phenyl-2-butanol in a ratio of 54:1.
