  R3Si−X (X = Cl, Br, I) to platinum(0) complexes PtLn (L = tertiary phosphine) yielded trans-R3SiPtXL2 species. Halosilanes exhibited the following orders of reactivities:  for Me3SiX, X = Cl (no reaction) << Br < I, and for Me4-nSiCln, n = 1 (no reaction) << 2 < 3. The reactivities of platinum complexes increased in the order of Pt(PPh3)4, Pt[Ph2P(CH2)2PPh2]2 (no reactions) << Pt(PMe2Ph)4 < Pt(PMe3)4

  2- or 3-Alkenenitriles, (R1R2HC)R3C=CHCN or R1R2C=CR3CH2CN (R1, R2, R3 = H, Me, etc.), react with iodosilanes, R4Me2SiI (R4 = Me, Me3Si), in the presence of Et3N to give 2-silyl-2-alkenenitriles, (R1R2HC)R3C=C(SiMe2R4)(CN), in good to moderate yields with high E selectivity (R3 = H). A 2-methylalkenenitrile, H2C=CHCHMe(CN) or MeCH=CMe(CN), is silylated with Me3SiI to provide a 4-silyl-2-alkenenitrile, Me3SiCH2CH=CMe(CN).

  2-或3-烯腈，（R1R2HC）R3C=CHCN或R1R2C=CR3CH2CN（R1，R2，R3 = H，Me等），在Et3N的存在下与碘硅烷R4Me2SiI（R4 = Me，Me3Si）反应，生成2-硅基-2-烯腈，（R1R2HC）R3C=C(SiMe2R4)(CN)，产率良好到中等，且具有高E选择性（R3 = H）。一种2-甲基烯腈H2C=CHCHMe(CN)或MeCH=CMe(CN)与Me3SiI反应，生成4-硅基-2-烯腈Me3SiCH2CH=CMe(CN)。
• Dichotomous Reactivity of Halodisilanes in Oxidative Addition with Pt(PEt₃)₃. Formation of Bis(silyl)- or (Disilanyl)platinum Complexes

  日期：1990.8

  The Si-Si bond in XSiMe2SiMe2Y (X, Y = F, F; Cl, Cl; Cl, Me; Br, Me) was readily cleaved with Pt(PEt3)3 to give cis-(XMe2Si)(YMe2Si)Pt(PEt3)2 complexes. On the other hand, ISiMe2SiMe3 selectively underwent oxidative addition at the Si–I bond to result in the formation of trans-(Me3SiMe2Si)PtI(PEt3)2.

  XSiMe2SiMe2Y (X, Y = F, F; Cl, Cl; Cl, Me; Br, Me) 中的 Si-Si 键很容易被 Pt(PEt3)3 裂解，得到顺式-(XMe2Si)(YMe2Si)Pt(PEt3 )2 复合体。另一方面，ISiMe2SiMe3 在 Si-I 键上选择性地进行氧化加成，导致形成反式-(Me3SiMe2Si)PtI(PEt3)2。

• Pd-Catalyzed Coupling Reaction of Acetylenes, Iodotrimethylsilane, and Organozinc Reagents for the Stereoselective Synthesis of Vinylsilanes

  The reaction of terminal acetylenes with Me(3)SiI (1) and organozinc reagents in the presence of Pd(PPh(3))(4) results in addition of the trimethylsilyl group of 1 and an alkyl group of the organozinc reagent to the acetylenes. In all cases the trimethylsilyl group adds to the terminal carbon of the acetylenes. Both aromatic and aliphatic terminal acetylenes undergo the coupling reaction with high regio- and stereoselectivities. The yield and stereoselectivity are relatively sensitive to the nature of the organozinc reagent used. The reaction of phenylacetylene (2) using Bu(2)Zn gives the corresponding coupling product in high yield with high stereoselectivity (>98%). In contrast, the use of BuZnI results in 92% stereoselectivity. The stereoselectivity for the reaction using (Me(3)-SiCH2)(2)Zn is lower than those for Me(2)Zn, Et(2)Zn, and Bu(2)Zn. For organozinc reagents, alkylzinc works well while phenyl-, ethynyl-, and allylzinc do not. The reaction using Me(3)SiCl, Me(3)SiBr, Me(3)SiSPh, Me(3)SiSePh, and Me(3)SiOTf in place of 1 does not proceed. The reaction with Me(3)SiMe(2)-SiI and Me(3)SiMe(2)SiMe(2)SiI in place of 1 gives the corresponding vinyldisilane and -trisilane, respectively.
