  Photochemical reactions of [(Ph3P)2ReH7] and [(Ph2PCH2CH2PPh2)ReH7]

  摘要：

  [(Ph3P)2ReH7] (Ia) reacted in tetrahydrofuran with cyclopentadiene or cyclohexa-1,4-diene under UV irradiation to give [(Ph3P)(eta-C5H5)ReH4] (II), and a 1:2 mixture of [(Ph3P)2(eta-C6H6)ReH] and [(Ph3P)(eta-C6H6)ReH3] (III), respectively; III was isolated from the photochemical reaction of Ia with 3,3-dimethylbutene in benzene. When using [(dppe)ReH7] (Ib) (dppe = Ph2PCH2CH2PPh2) instead of Ia in these three reactions, no cyclopentadienyl compound was obtained, but [(dppe)(eta-C6H6)ReH] (IV) and [(dppe)(eta-C6H6)ReCH2CH2CMe3] (V) were isolated; IV and V are precursors to arene and cyclohexadienylrhenium derivatives containing dppe.

  The reaction of K[H(6)ReL(2)] with [RuHCl(CO)(PPh(3))(3-x)P(OPri}3)(x)](L(2) = (PMePh(2))(2), dppe,(AsPh(3))(2), or (PPh(3))(2); x = 0, 1 or 2) leads to [L(2)(CO)HRe(mu-H)(3)RuH(PPh(3))(2-y)P(OPri)(3)}(y)](x = 0 or 1, y = 0; x = 2, y = 1(L(2) = PPh(3))) in a first step. Under the reaction conditions most of these complexes react rapidly with the liberated phosphine giving [L(2)(CO)Re(mu-H)(3)Ru(PPh(3))(3-y)-P(OPri)(3))(y)] (L(2) = (PMePh(2))(2) or dppe, y = 0; L(2) = (PPh(3))(2) y = 1) as the only isolable complexes. The structure of [(PMePh(2))(2)(Co)Re(mu-H)(3)Ru(PPh(3))(3)] has been established by X-ray structure analysis. The complex [(PPh(3))(2)(CO)Re(mu-H)(3)Ru(PPh(3))(2)(P(OPri)(3))] reacts with molecular hydrogen under pressure to generate [L(2)(CO)HRe(mu-H)(3)RuH)PPh(3))(P(OPri)(3)) as the sole product.
