  be very effective for the formation of monocyclic titanacyclopentenes in excellent yields. On the other hand, a combination of Cp2TiCl2–2n-BuLi was used for intermolecular coupling of two alkynes to form titanacyclopentadienes in good to excellent yields. A reaction temperature range from −10 to −30 °C was critical for the success of the combinations. Reactions of these in situ-prepared titanacycles

  发现Cp 2 TiCl 2 –2EtMgBr的组合对于形成单环钛环戊烯非常有效，并且产率很高。另一方面，将Cp 2 TiCl 2 –2 n -BuLi的组合用于两个炔烃的分子间偶联，形成钛环戊二烯，收率好至极好。-10至-30°C的反应温度范围对于组合的成功至关重要。这些原位制备的钛环化合物的反应显示出与它们的氧化锆环类似物有趣或相似的区别。

  The oxidative conversion of silyl enol ethers to α,β-unsaturated ketones using a less-hindered class of oxoammonium salts (AZADO+BF4–) is described. The reaction proceeds via the ene-like addition of oxoammonium salts to silyl enol ethers.

• Catalytic Intermolecular Pauson−Khand-Type Reaction:  Strong Directing Effect of Pyridylsilyl and Pyrimidylsilyl Groups and Isolation of Ru Complexes Relevant to Catalytic Reaction

  Some circumstantial evidence for the directing effect of the 2-pyridylsilyl group in the Ru-catalyzed intermolecular Pauson-Khand-type reaction (PKR) of alkenyl(2-pyridyl)silane, alkyne, and carbon monoxide has been provided. Most importantly, we have succeeded in isolating several monometallic Ru complexes relevant to the catalytic reaction: Ru(vinylsilane)(CO)(3) complexes and ruthenacyclopentene. While the stoichimetric reaction of the Ru(vinylsilane)(CO)(3) complex with an alkyne led to the formation of the corresponding cyclopentenone (PKR product) at 100 degreesC, the ruthenacyclopentene intermediate was quantitatively produced at 50 degreesC. This complex was also converted to a cyclopentenone upon heating at 100 degreesC. Moreover, it was also found that the Ru(vinylsilane)(CO)(3) complex and ruthenacyclopentene serve as catalysts in intermolecular PKR.
