A new class of compounds is disclosed that in preferred embodiments relate to Ru-based catalysts suitable for use in olefin metathesis reactions. Such compounds demonstrate high rates of catalytic turnover in comparison with other Ru catalysts known in the art. Moreover, the catalysts are highly stable, and readily suited to attachment to a solid support via the anionic ligands. In preferred embodiments the compounds present significant advantages by permitting facile isolation of active catalyst. The invention also pertains to methods of producing the catalysts, and their use in catalyzing olefin metathesis reactions.

A ferrocene‐tagged rutheniumcarbene 15 that can be reversibly immobilized in an ionicliquid (IL) via the controlled oxidation and reduction of a ferrocene tag was prepared. This offers a new strategy which uses redox chemistry to controlimmobilization and to recycle both the catalyst and the IL. In this experiment, 11 recycles were performed for the ring‐closing metathesis (RCM) of a substrate using

A homogeneous ruthenium–carbene complex was tagged with a light‐responding nitrobenzospiropyran group to control its solubility through reversible conversion between its neutral (lipophilic) and ionic (lipophobic) states using light irradiation (see scheme; Mes=mesityl). This tagged complex has significant catalytic activity in ring‐closing metathesis reactions and was recycled several times.
均匀的钌-卡宾络合物带有一个光响应性硝基苯并螺吡喃基团,以通过使用光辐照在其中性(亲脂性)和离子性(疏脂性)状态之间可逆转换来控制其溶解度(参见方案; Mes = mesityl)。这种标记的复合物在闭环复分解反应中具有显着的催化活性,并被回收了数次。
A first generation Hoveyda–Grubbsrutheniumcomplex with a closo-1,2-C2B10H11 tag has been prepared. This new catalyst was tested in ring-closing metathesis (RCM) reactions and proved to be quite efficient. In addition, the recovery and reuse of a previously reported second generation Hoveyda–Grubbsrutheniumcarbenecomplex bearing an ionic [nido-7,8-C2B9H10]− tag was further studied. When used in
制备了带有closo-1,2-C 2 B 10 H 11标签的第一代Hoveyda-Grubbs钌络合物。该新型催化剂已在闭环复分解(RCM)反应中进行了测试,并被证明非常有效。另外,还对先前报道的带有离子[nido-7,8-C 2 B 9 H 10 ] -标记的第二代Hoveyda-Grubbs钌卡宾络合物的回收和再利用进行了研究。当用于离子液体中时,该催化剂可以方便地回收和再利用,而对含二或三取代双键的含氧和N保护的底物的RCM活性仅有非常轻微的损失。

A rutheniumcarbene complex containing a Zn‐porphyrin ligand has been developed. The complex was characterized by 1H NMR, IR, HRMS and elemental analysis. The catalytic activity of the rutheniumcarbene complex for olefin metathesis reactions was also investigated. The complex exhibited excellent performance for both ring‐closing and cross metathesis reactions at 35°C.
已开发出含有锌卟啉配体的钌卡宾络合物。该复合物通过1 H NMR,IR,HRMS和元素分析进行表征。还研究了钌卡宾配合物对烯烃复分解反应的催化活性。该复合物在35°C的闭环和交叉易位反应中均表现出出色的性能。
