  日期：——

  efficient and simple coupling reactions of benzylic and aryl bromides with aluminium acetylide catalyzed by NiCl(2)(PPh(3))(2) are reported. The coupling reactions proceed at room temperature employing 4 mol% catalyst, affording coupling products in excellent yields of up to 95% in short reaction times. The system worked efficiently with aryl and heterocyclic bromides as well.

  Synthetic methods for the in-situ formation of olefin metathesis catalysts are disclosed, as well as the use of such catalysts in metathesis reactions of olefins and olefin compounds. In one aspect, a method is provided for synthesizing an organometallic compound of the formula (I); comprising contacting a precursor compound of the formula (X1X2MLjL1kL3m)i with an acetylenic compound of the formula comprising a chelating moiety, optionally, in the presence of a neutral electron donor, wherein M is a Group 8 transition metal, L, L1, L2, and L3 are neutral electron donors, X1 and X2 are anionic ligands,j is 1, 2, or 3; k is zero, 1, or 2; m is zero or 1; n is 1 or 2; and i is an integer; with the proviso that k is zero when the precursor compound is contacted with the acetylenic compound in the presence of the neutral electron donor, and R1 and R2 are independently selected from hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, substituted heteroatom-containing hydrocarbyl, and functional groups, wherein R1 and R2 are linked and together form one or more cyclic groups, R2 and L2 are linked and together form one or more cyclic groups, and any other two or more of X1, X2, L1, L2, L3, R1, and R2 can be taken together to form one or more cyclic groups. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry.
