    摘要: A synthetic method leading to the isolation of ruthenium-based olefin metathesis catalysts relies on the cross metathesis reaction between (L1)Ru(L2)(3-phenylindenylid-1-ene)Cl2 (where L1 and L2 can be two-electron donors) and an olefin. This method leads to the isolation of numerous ruthenium olefin metathesis catalysts.

    摘要: Gold (I) hydroxide complexes of the form Z—Au—OH and digold complexes of the form Z—Au-(μOH)—Au—Z where groups Z are two electron donors are provided. The groups Z may be carbenes, for example nitrogen containing heterocyclic carbenes (NHCs), phosphines or phosphites. The complexes can be used as catalysts, for example in reactions such as hydration of nitriles, skeletal arrangement of enynes, alkoxycyclisation of enynes, alkyne hydration, the Meyer-Shuster reaction, 3,3′ rearrangement of allylic acetates, cyclisation of propargylic acetates, Beckman rearrangements and hydroamination. The complexes can be used in medicine, for example in the treatment of cancer.

    摘要: This invention provides a process for conducting Stille coupling reactions. The processes of the present invention make use of N-heterocyclic carbenes as ancillary ligands in Stille couplings of aryl halides. A Stille coupling can be carried out by mixing, in a liquid medium, at least one strong base; at least one aryl halide or aryl pseudohalide in which all substituents are other than stannyl groups, wherein the aryl halide has, directly bonded to the aromatic ring(s), at least one halogen atom selected from the group consisting of a chlorine atom, a bromine atom, and an iodine atom; at least one organotin compound wherein the tin atom is quaternary, wherein one group bound to the tin atom is unsaturated at the alpha or beta position, and wherein each of the remaining groups bound to the tin atom is a saturated group; at least one metal compound comprising at least one metal atom selected from nickel, palladium, and platinum, wherein the formal oxidation state of the metal is zero or two; and at least one N-heterocyclic carbene. One preferred type of N-heterocyclic carbene is an imidazoline-2-ylidene of the formula wherein R1 and R2 are each, independently, alkyl or aryl groups having at least 3 carbon atoms, R3 and R4 are each, independently, a hydrogen atom, a halogen atom, or a hydrocarbyl group.
