    • Ruthenium and osmium carbene compounds that are stable in the presence of a variety of functional groups and can be used to catalyze olefin metathesis reactions on unstrained cyclic and acyclic olefins are disclosed. Also disclosed are methods of making the carbene compounds. The carbene compounds are of the formula where M is Os or Ru; R1 is hydrogen; R is selected from the group consisting of hydrogen, substituted or unsubstituted alkyl, and substituted or unsubstituted aryl; X and X1 are independently selected from any anionic ligand; and L and L1 are independently selected from any neutral electron donor. The ruthenium and osmium carbene compounds of the present invention may be synthesized using diazo compounds, by neutral electron donor ligand exchange, by cross metathesis, using acetylene, using cumulated olefins, and in a one-pot method using diazo compounds and neutral electron donors. The ruthenium and osmium carbene compounds of the present invention may be used to catalyze olefin metathesis reactions including, but not limited to, ROMP, RCM, depolymerization of unsaturated polymers, synthesis of telechelic polymers, and olefin synthesis.

    • The present invention generally relates to the discovery that the solubility of metal complexes may be readily manipulated by the addition of one or more solubility-enhancing compounds. This manipulation of the solubilities allows for the preparation of suitable samples for precise quantitative analysis and for the facile purification of the desired products from the reaction mixture containing one or more metal complexes. In one embodiment of the invention, the relative solubilities between two solutions are manipulated so as cause the metal complex found in a first solution to transfer to a second solution that is generally immiscible with the first solution. The metal complex is thus separated from the reaction mixture which comprises the first solution by the removal of the second solution. In another embodiment, the solubility-enhancing compounds of the present invention is used to prepare samples containing metal complexes for precise quantitative analysis such as inductively coupled plasma mass spectroscopy.
    • 本发明一般涉及金属配合物的溶解度可以容易地通过加入一种或多种溶解度增强化合物来操作的发现。 这种溶解度的操作允许制备合适的样品以进行精确的定量分析,并且从含有一种或多种金属络合物的反应混合物中容易地纯化所需产物。 在本发明的一个实施方案中,操作两种溶液之间的相对溶解度,使得在第一溶液中发现的金属络合物转移到通常与第一溶液不混溶的第二溶液。 因此,金属络合物通过除去第二溶液与包含第一溶液的反应混合物分离。 在另一个实施方案中,本发明的溶解度增强化合物用于制备含有金属络合物的样品以进行精确的定量分析,例如电感耦合等离子体质谱法。

    • The present invention relates to the synthesis of highly active ruthenium and osmium carbene metathesis catalyst in good yield from readily available starting materials. The catalysts that may be synthesized are of the general formula wherein: M is ruthenium or osmium; X and X1 are independently any anionic ligand; L and L1 are any neutral electron donor ligand; and, R and R1 are each hydrogen or one of the following substituent groups: C2-C20 alkenyl, C2-C20 alkynyl, C1-C20 alkyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkenyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkylsulfonyl and C1-C20 alkylsulfinyl. Optionally, the substituent group may be substituted with one or more groups selected from C1-C5 alkyl, halogen, C1-C5 alkoxy, and aryl. When the substitute aryl group is phenyl, it may be further substituted witn one or more groups selected from a halogen, a C1-C5 alkyl, or a C1-C5 alkoxy. Specific synthetic protocols for vinyl alkylidene catalysts wherein R is hydrogen and R1 is —CHCR12R13 and non-vinyl alkylidene catalysts are also disclosed. In addition to the ease of synthesis (typically a one-step synthesis), the reactions generally may be run at or above room temperature and the resulting products usually may be used without extensive post synthesis purification.
