  as good catalyst precursors for ring-opening metathesis polymerization (ROMP) of norbornene, substituted norbornenes, polycyclic alkenes and cyclooctene and ring-closing metathesis (RCM) of α,ω-dienes. Furthermore, these precursors possess extremely high stability toward air, heat and moisture in comparison with other metathesis-active alkylidene ruthenium systems. No significant catalyst decomposition

  relevant olefin metathesis initiator, which circumvents the expensive, patent protected, often cumbersome preparative routes via Grubbs benzylidene complexes. Upon coordination of a Schiff base ligand to a second-generation ruthenium allenylidene complex, the formation of three catalyst isomers was observed. The major isomer was successfully isolated, and tested in a few olefin metathesis reactions

  这项工作的目的是开发一种与工业相关的烯烃复分解引发剂，该引发剂可通过Grubbs苄叉配合物来规避昂贵的，受专利保护的，通常繁琐的制备路线。在席夫碱配体与第二代钌亚烯基络合物配位后，观察到三种催化剂异构体的形成。成功分离出主要异构体，并在一些烯烃复分解反应中进行了测试。发现酸如HCl和HSiCl（3）可以促进复分解反应，但是原位形成的中性Ru碳炔络合物会限制催化能力。使用路易斯酸PhSiCl（3），避免了形成碳炔类，在环辛-1,5-二烯的开环复分解聚合中，营业额高达30,000。

  Interaction of Ru(=CHPh)(PCy3)(2)Cl-2 (Cy = cyclohexyl) with K[N(PPh2S)(2)] affords air-stable Ru(=CHPh)[N(PPh2S)(2)](2), 1, which has been characterized by X-ray diffraction. The Ru-C-alpha and average Ru-S distance for 1 are 1.88(2) and 2.377 Angstrom, respectively. Reaction of 1 with CO gives cis-Ru(CO)(2)[N(PPh2S)(2)](2). Complex 1 undergoes metathesis with ethyl vinyl ether to give the methoxycarbene complex Ru(=CHOEt)[N(PPh2S)(2)](2), 3. Treatment of Ru(=CHPh)(PCy3)(2)Cl-2 with K[N(PPh2Se)(2)] affords Ru(=CHPh)[PPh2NP(Se)Ph-2](2), 4, which has been characterized by X-ray crystallography The Ru-C, average Ru-P, and average Ru-Se distances are 1.873(8), 2.383, and 2.450 A, respectively. Reactions of Ru(=CHPh)(PCy3)(2)Cl-2 with K[P(OR)(2)S-2] afford cis-Ru(=CHPh)(PCy3)[P(OR)(2)S-2](2) (R = Et (6) and i-Pr (7)). Reaction of Ru(=CHPh)(PCy3)(2)Cl-2 with 1,4,7-trithiacyclononane ([9]aneS(3)) gives [([9]aneS(3))Ru(=CHPh)(PCy3)Cl]Cl, 8. Treatment of Ru(=C=CHPh)(PCy3)(2)Cl-2 with K[N(PPh2S)(2)] or [9]aneS(3) affords cis-Ru(=C=CHPh)(PCy3)[N(PPh2S)(2)](2) (9) or ([9]aneS(3))Ru(PCy3)Cl-2 (10), respectively. The Ru-C, Ru-P, and average Ru-S distances in 9 are 1.80(1), 2.420(3), and 2.479 Angstrom, respectively. Complexes 1 and 8 are active catalysts for ring-opening metathesis polymerization of norbornene.
