Alkene Metalates as Hydrogenation Catalysts.

ABSTRACT: First-row transition-metal complexes hold great potential as catalysts for hydrogenations and related reductive reactions. Homo- and heteroleptic arene/alkene metalates(1-) (M=Co, Fe) are a structurally distinct catalyst class with good activities in hydrogenations of alkenes and alkynes. The first syntheses of the heteroleptic cobaltates [K([18]crown-6)][Co(η⁴ -cod)(η² -styrene)₂ ] (5) and [K([18]crown-6)][Co(η⁴ -dct)(η⁴ -cod)] (6), and the homoleptic complex [K(thf)₂ ][Co(η⁴ -dct)₂ ] (7; dct=dibenzo[a,e]cyclooctatetraene, cod=1,5-cyclooctadiene), are reported. For comparison, two cyclopentadienylferrates(1-) were synthesized according to literature procedures. The isolated and fully characterized mono
