• Ni-Catalyzed Alkylative Dimerization of Vinyl Grignard Reagents Using Alkyl Fluorides

  Alkyl halides underwent unique cross-coupling reaction with vinylmagnesium chloride in the presence of Ni catalyst to give 2-alkyl-3-butenyl Grignard reagent (1) in high yields. This reaction proceeded efficiently at 25 degrees C in THF using primary and secondary alkyl fluorides. On the other hand, PhCH=CHMgBr gave double alkylative vinyl coupling product 4 in good yield as the sole coupling product

  烷基卤化物在 Ni 催化剂存在下与乙烯基氯化镁发生独特的交叉偶联反应，以高产率得到 2-烷基-3-丁烯基格氏试剂 (1)。该反应在 25 摄氏度的 THF 中使用伯和仲烷基氟化物有效进行。另一方面，PhCH=CHMgBr 以良好的产率得到双烷基化乙烯基偶联产物 4 作为唯一的偶联产物。与相应的氯化物、溴化物和碘化物相比，烷基氟是最合适的烷基化试剂。

• Synthesis of 1-Stannacyclopent-3-enes and Their Pyrolysis to Stannylenes

  1,1-Diorgano-1-stannacyclopent-3-enes have been synthesized by condensation in THF of magnesium complexes of 1,3-dienes and dichlorodiorganostannanes. 1, 1-Dimethyl-, 1, 1-di-n-butyl-,1, 1-di-tert-butyl-, and 1,1-diphenyl-1-stannacyclopent-3-enes and 1,1,3,4-tetramethyl-, 1,1-di-tert-butyl-3,4-dimethyl-, and 3,4-dimethyl-1,1-diphenyl-1-stannacyclopent-3-enes were prepared. Kinetic studies of the pyrolysis. at temperatures as low as 75 degrees C of several of these stannacyclopent-3-enes resulted in their first-order disappearance, consistent with a unimolecular dissociation to the corresponding stannylene and diene. Activation parameters are reported. Trapping of dimethylstannylene by dienes was overwhelmed by oligomerization of Me2Sn::, but for t-Bu2Sn: a high yield of diene adduct was obtained. The dimethylstannylene oligomer(s) functioned as stannylenoids and were responsible for several reactions previously attributed to free Me2Sn:. cyclo-(t-Bu2Sn)(4) may also function as a stannylenoid.

  3-Arsolenes R-As-CH2-C(Me)=C(R')-CH, (R = Ph, Me, (t)Bu, Cl, R' = H, Me) are readily obtained from zirconocene-butadiene complexes and RAsCl2. Alkylation with methyl iodide gives arsonium salts [R(Me)As-CH2-C(Me)=C(R')-CH2]I (R = Ph, Me, (t)Bu, R'= H, Me), treatment with sulphur gives sulphides R(S)As-CH2-C(Me)=C(Me)-CH, (R = Me, (t)Bu), while oxidation with Br, or SO2Cl2 results in ring cleavage. From chloroarsolene Cl-As-CH2-C(Me)=((Me)-CH2 substitution products R-As-CH2-C(Me)=C(Me)-CH2 (R = 1, H, SPh, OMe, NMe2) as well as coupling products with As-As, As-0-As, and As-S-As units were synthesized. In addition, a number of arsolene complexes with the metals chromium, molybdenum, tungsten, and ruthenium is described.
