    • The present invention provides methods for the synthesis of catalysts and precursors thereof. Methods of the invention may comprise combining a catalyst precursor and at least one ligand to generate a catalytically active species, often under mild conditions and in high yields. In some cases, a wide variety of catalysts may be synthesized from a single catalyst precursor. Methods of the invention may also include the preparation of catalysts which, under reaction conditions known in the art, may have been difficult or impossible to prepare and/or isolate due to, for example, steric crowding at the metal center. The present invention also provides catalyst compositions, and precursors thereof, which may be useful in various chemical reactions including olefin metathesis. In some cases, methods of the invention may reduce the number of synthetic and purification steps required to produce catalysts and/or other reaction products, as well as reducing time, cost, and waste production.
    • 本发明提供合成催化剂及其前体的方法。 本发明的方法可以包括将催化剂前体和至少一种配体结合以产生催化活性物质,通常在温和条件下和高产率下。 在一些情况下,可以从单一催化剂前体合成多种催化剂。 本发明的方法还可以包括催化剂的制备,其在本领域已知的反应条件下可能由于例如在金属中心的空间拥挤而难以或不可能制备和/或分离。 本发明还提供催化剂组合物及其前体,其可用于包括烯烃复分解的各种化学反应。 在一些情况下,本发明的方法可以减少制备催化剂和/或其它反应产物所需的合成和纯化步骤的数量,以及减少时间,成本和废物的产生。
