  A New Rhodium(I) Hexapentaene Complex Prepared from a Precursor Containing a RhC₅ Chain

  摘要：

  The metallacumulene [RhCl(=C=C=C=C=CPh2)(PiPr(3))(2)] (6) was prepared stepwise from [RhCl(PiPr(3))(2)](2) (1) and HC=CC=CCPh2OSiMe3 via the pi-alkyne complex 2, the diynylhydridorhodium(III) species 3, and the vinylidenerhodium(I) compound 4 as intermediates. The reaction of 6 with CH2N2 affords true isomers (A and B) of the square-planar rhodium(I) complex 7, in which the hitherto unknown hexapentaene H2C=C=C=C=C=CPh2 is n-coordinated to the RhCl(PiPr(3))(2) fragment.

  The vinylidene complex trans-[RhCl(CCHCCCPh2OSiMe3)(PiPr3)2] (5), prepared from [RhCl(PiPr3)2]2 (1) and HCCCCCPh2OSiMe3 (2), is in equilibrium with the pentatetraenediyl isomer trans-[RhCl(CCCCHCPh2OSiMe3)(PiPr3)2] (6) in benzene solution. The reaction of the diynyl(hydrido) compound [RhH(Cl)(CCCCCPh2OSiMe3)(PiPr3)2(py)] (7) with triflic acid in THF/water afforded the functionalized rhodium(I) vinylidene trans-[RhCl(CCHC(O)CHCPh2)(PiPr3)2] (9), which was also obtained from the metallacumulene trans-[RhCl(CCCCCPh2)(PiPr3)2] (8) under analogous conditions.

  由 [RhCl(PiPr3)2]2 (1) 和 HCCCCCPh2OSiMe3 (2) 制备的亚乙烯基复合物反式-[RhCl(CCHCPh2OSiMe3)(PiPr3)2] (5) 与五亚甲基异构体反式-[RhCl(CCCCHCPh2OSiMe3)(PiPr3)2] (6) 在苯溶液中处于平衡状态。二炔基（氢化物）化合物[RhH(Cl)(CCCCCPh2OSiMe3)(PiPr3)2(py)](7) 与三氟甲酸在 THF/水中反应，得到了功能化亚乙烯基反式-[RhCl(CCHC(O)CHCPh2)(PiPr3)2](9)、反式-[RhCl(CCCCCPh2)(PiPr3)2] (8)也是在类似条件下从金属铝得到的。
