Patent ID: 7553924

Claim:
A method for carbon-carbon bond formation, comprising forming of the carbon-carbon bond with a catalyst comprising a metal complex comprising a ligand Land a metal center M 1 ; wherein M 1 is selected from the group consisting of transition metal, Li, Na, K, Mg, Ca, Al, and Ga; the ligand L is represented by the following general formula I wherein: B represents H or a bond; A represents a ring or heterocyclic ring, and said ring or heterocyclic ring is unsubstituted or substituted with X 1 to X n ; X 1 to X 1 , for each occurrence independently represent one or more groups selected from the group consisting of hydrocarbons, PR 1 R 2 , NR 1 R 2 , OR 1 , SR 1 , and AsR 1 R 2 ; Y represents a group selected from the group consisting of PR 1 R 2 , NR 1 R 2 , OR 1 , SR 1 , and AsR 1 R 2 ; n represents an integer larger than or equal to 1; R 1 and R 2 for each occurrence independently represent saturated or unsaturated hydrocarbon or aromatic groups with or without heteroatoms of O, S, N, P or As; and the linkage between N—Y is a saturated or unsaturated hydrocarbon or aromatic group with or without substituents; and wherein, if the carbon-carbon bond formation comprises a Heck coupling of aryl halides and alkenes, the carbon-carbon bond formation is a coupling of aryl halides with styrene according to the following reaction Heck coupling of aryl halides with styrene: wherein: R 7 represents H, NO 2 , CHO, C(O)R 1 , halogen, OR 1 , or NR 1 ; Hal 4 represents halogen; and R 1 represents saturated or unsaturated hydrocarbon groups with or without substituents or saturated or unsaturated aromatic groups with or without substituents.
