• Migrations in a Polysilyl Complex of Rhodium. Trapping of an Apparent Silylene Intermediate and Observation of Reversible Si−Si Bond Reductive Elimination

  日期：1996.8.6

  Reaction of (Me(3)P)(3)RhCl with (THF)(3)LiSi-(SiMe(3))(3) in the presence of 2-butyne or diphenylacetylene generates (Me(3)P)(2)(Me(3)Si)RhSiMe(2)C(R)=C(R)SiMe(SiMe(3)) (1, R = Me; 2, R = Ph). These complexes undergo a fluxional process which exchanges the SiMe(3) groups, apparently by Si-Si bond reductive elimination/oxidative addition.
• Synthesis and reactions of silyl and germyl derivatives of scandocene. Structure of Cp2Sc[Si(SiMe3)3](THF)
  作者：Brian K. Campion、Richard H. Heyn、T. Don Tilley

  日期：1993.7

  The scandocene complexes Cp2Sc(ER3)(THF) (ER3 = Si(SiMe3)3 (1), Si(SiMe3)2Ph (2), Si(t)BuPh2 (3), SiPh3 (4), Ge(SiMe3)3 (5)) have been prepared by addition of the appropriate silyl- or germyllithium reagent to [Cp2ScCl]2. The crystal structure of 1 revealed no unusual distortions in the molecule and a Sc-Si bond length of 2.683(2) angstrom. These unusually reactive d0 silyl complexes polymerize ethylene, and 1 reacts with phenylacetylene via sigma-bond metathesis to give HSi-(SiMe3)3 and the known acetylide [CpScC=CPh]2. Complexes 1, 3, and 5 react with CO via CO-CO coupling processes, to give the scandoxyketene derivatives (Cp2ScO)(R3E)C=C=O, which are trapped as the adducts Cp2Sc[OC(ER3)C(L)O] (6, ER3 = Si(SiMe3)3, L = Me-THF; 10, ER3 = Ge(SiMe3)3, L = THF; 11, ER3 = Si(SiMe3)3, L = PMe2Ph). In nonpolar media, carbonylations of 1, 3, and 5 give the enedione diolate structures [Cp2ScOC(ER3)CO]2 (ER3 = Si(SiMe3)3 (7), Si(t)BuPh2 (8), Ge(SiMe3)3 (9)). The insertion of CN-2,6-Me2C6H3 (CNXyl) into the Sc-Si bond of 1 provides the stable pi2-iminosilaacyl complex Cp2Sc[eta2-CN(Xyl)Si(SiMe3)3] (12), which reacts with PhC=CH to afford [Cp2ScC=CPh]2 and the formimidoylsilane HC(N-2,6-Me2C6H3)Si(SiMe3)3 (13). Finally, 12 reacts with a second equivalent of CNXyl to form Cp2ScN(Xyl)C(SiMe3)=CN=CCMe=CHCH=CHCMe[Si(SiMe3)2]} (14), which appears to result from rearrangement of the intermediate ketenimine (Cp2ScNXyl)[(Me3Si)3Si]C=C=NXyl via (1) migration of SiMe3 from the Si(SiMe3)3 group to the alpha-carbon of the ketenimine and (2) addition of the resulting C=Si(SiMe3)2 double bond to an adjacent xylyl ring.
