Abstract

Palladium-catalyzed Sonogashira coupling reactions of the neutral [eta(5)(1-5)-1-ethynyl-4-methoxycyclohexa-2,4-dienyl]tricarbonylmanganes e(I) (4) and (eta(6)-chlorobenzene)tricarbonylchromium (5) yields the dinuclear 1-[eta(6)-phenylethynyl]tricarbonylchromium-[eta(5)(1-5)-methoxycyclohex a-2,4-dienyl]tricarbonylmanganese complex 6, which upon hydride abstraction affords the corresponding dinuclear diphenylacetylene eta(6)-Mn/eta(6)-Cr complex 7. This study has been extended to the case of dinuclear eta(6)-Mn/eta(6)-Cr linked to different spacers comprising a thiophene, a triple bond, or a combination of them.
