  A comparison of electron transfer reagents in the reductive opening of epoxides: reasons for the superiority of titanocene based complexes

  摘要：

  Several commonly used electron transfer reagents were compared in their reactivity towards three epoxides. These substrates were designed to allow for a distinction between competing courses of the reaction. It was found that titanocene reagents were clearly superior due to their low Lewis acidity, high reduction tendency towards epoxides, and low reduction tendency towards the pivotal P-metal oxy radical intermediates.

• Ruthenium-Catalyzed [2+2+2] Cycloaddition of 1,6-Enynes and Unactivated Alkynes: Access to Ring-Fused Cyclohexadienes

  The [2+2+2] intermolecular carbocyclization reactions between 1,6‐enynes and alkynes catalyzed by [RuCl(cod)(Cp*)] (cod=1,5‐cyclooctadiene, Cp*=pentamethylcyclopentadienyl) are reported to provide bicyclohexa‐1,3‐dienes. The presented reaction conditions are compatible with internal and terminal alkynes and the chemo‐ and regioselectivity issues are controlled by the presence of substituents at the

• Ruthenium-Catalyzed Hydroalkynylative Cyclization of 1,6-Enynes Induced by Substituent Effects

  alkyne proceeds smoothly at room temperature to afford highly substituted five-membered cyclic compounds featuring a 1,5-enyne motif. Deuterium-labeling experiments showed that the key ruthenacyclopentene intermediate undergoes cleavage of metal–carbon bonds through the metal-assisted σ-bond metathesis reaction, thus leading to the formation of C(sp2)–H and C(sp3)–C(sp) bonds.

  在大体积取代的末端炔烃存在下，钌催化的1,6-烯炔环化在室温下平稳进行，从而得到具有1,5-烯炔基序的高度取代的五元环化合物。氘标记实验表明，关键的钌环戊烯中间体通过金属辅助的σ键复分解反应经历了金属-碳键的裂解，从而导致C（sp 2）-H和C（sp 3）-C（ sp）债券。

  A new active three-component catalytic system for enyne metathesis is reported. It is easily generated in situ by combination of [RuCl2(p-cymene)]2, 1,3-bis(mesityl)imidazolium chloride and Cs2CO3 and exhibits excellent performance for the intramolecular metathesis reaction even from highly substituted enynes.
