摘要

The unsaturated trihydrido complex [(C6Me6)(2)Ru-2(mu(2)-H)(3)](+) reacts with diaryl- or dialkyl-phosphines PR2H to give the dinuclear cations [(C6Me6)(2)Ru-2(mu(2)-PR2)(mu(2)-H)(2)](+) (R= Ph, 1; R = t-Bu, 2). Surprisingly, complexes of the type [(C6Me6)(2)Ru-2(mu(2)-PR2)(mu(2)-H)(2)](+) with R = Ph (1), n-Bu (3), n-Oct (4) are also accessible in high yield from the reaction of [(C6Me6)(2)Ru-2(mu(2)-H)(3)](+) with the corresponding triaryl- or trialkylphosphine PPh3, P(n-Bu)(3), or P(n-Oct)(3) by carbon-phosphorus bond cleavage. A possible intermediate of the reaction with PPh3, [(C6Me6)(2)Ru-2(mu(2)-PPh2)(mu(2)-H)(mu(2)-Ph)](+) (5), could be isolated from the reaction mixture as the tetrafluoroborate salt, the single-crystal X-ray structure analysis of which reveals a bridging phenyl ligand coordinated in an mu(1)-mu(2) fashion to the diruthenium backbone. With the mixed phosphine PMe2Ph, [(C6Me6)(2)Ru-2(mu(2)-H)(3)](+) reacts to give [(C6Me6)(2)Ru-2(mu(2)-PMe2)(mu(2)-H)(2)](+) (6) and the corresponding intermediate [(C6Me6)(2)Ru-2(mu(2)-PMe2)(mu(2)-H)(mu(2)-Ph)](+) (7). All dinuclear cations are isolated as the tetrafluoroborate salts.
