  摘要：

  The symmetric d(5) trans-bis(alkynyl) complexes [Mn(R'2PCH2CH2PR'(2))(2)(C CR)(2)] (R'= Me, R = SiEt3, 3a; R' = Me, R = (SiPr3)-Pr-i, 3b; R' = Me, R = Si(Bu-t)Me-2, 3c; R' = Et, R = SiEt3, 4a; R' = Et, R = (SiPr3)-Pr-i, 4b; R' = Et, R = Si(Bu-t)Me-2, 4c) can be prepared by the reaction of [Mn(R'2PCH2CH2PR'(2))(2)Br-2] (R' = Me, 1; R' = Et, 2) with 2 equiv of LiC CR (R = SiEt3, (SiPr3)-Pr-i, Si(Bu-t)Me-2). The reactions of species 3 and 4 with [Cp2Fe] [PF6] yield the corresponding d4 complexes [Mn(dmpe)(2)(C CR)(2)] [PF6] (R' = Me, R = SiEt3, 5a; R' = Me, R = (SiPr3)-Pr-i, 5b; R' = Me, R = Si(Bu-t)Me-2, 5c; R' = Et, R = SiEt3, 6a; R' = Et, R = (SiPr3)-Pr-i, 6b; R' = Et, R = Si(Bu-t)Me-2, 6c). The asymmetrically substituted trans-bis(alkynyl) complexes [Mn(dmpe)(2)(C CR)(C CH)] [PF6] (R' = Me, R = SiEt3, 10a; R' = Me, R = (SiPr3)-Pr-i, 10b; R' = Me, R = Si(Bu-t)Me-2, 10c) are prepared by the reaction of the vinylidene compounds Mn(dmpe)(2)(C CR)(C CH2) (R' = Me, R = SiEt3, 9a; R' = Me, R = (SiPr3)-Pr-i, 9b; R' = Me, R = Si(Bu-t)Me-2, 9c) with 2 equiv of [Cp2Fe] [PF6] and 1 equiv of quinuclidine. The mixed-valent complexes [{Mn(dmpe)(2)(C CR)}(2)(mu-C-4)] [PF6] [11](+) are obtained by the reaction of 10 with 1 equiv of DBU (1,8-diazabicyclo[5.4.0]undec-7-ene). The neutral dinuclear Mn(II)/Mn(II) compounds [{Mn(dmpe)(2)(C CR)}(2)(mu-C-4)] (R = SiEt3, 11a; R = (SiPr3)-Pr-i, 11b; R = Si(Bu-t)Me-2, 11c) are synthesized by the reduction of [11](+) with Co(C5Me5)(2). Complexes [11](+) can also be oxidized with [Cp2-Fe] [PF6] to produce the dicationic Mn(III)/Mn(III) species [{Mn(dmpe)(2)(C CR3)}(2)(mu-C-4)] [PF6](2) (R = SiEt3, [11a](2+); R = (SiPr3)-Pr-i, [11b](2+); R = Si(Bu-t)Me-2, [11c](2+)). Both redox processes are fully reversible. The dinuclear compounds have been characterized by NMR, IR, and Raman spectroscopy, cyclic voltammetry, and elemental analyses. X-ray diffraction studies have also been performed on several complexes.
