20080269514 | Iron or Cobalt-Catalyzed Carbon-Carbon Coupling Reaction of Aryls, Alkenes and Alkines With Copper Reagents - The present invention relates to a process for the formation of carbon-carbon bonds starting from a copper compound of an aryl, heteroaryl, alkene or alkine and an aryl, heteroaryl, alkene or alkine compound having a suitable leaving group. The copper compounds can be prepared inter alia by means of transmetalliziation from a Grignard or lithium compound. Cross-coupling of these compounds with e.g. a halogen-substituted aryl compound is carried out by means of an iron or cobalt catalyst using suitable solvents and suitable additives. | 10-30-2008 |

20140031545 | ORGANOZINC COMPLEXES AND PROCESSES FOR MAKING AND USING THE SAME - Processes for making an organozinc reagents are disclosed comprising reacting (A) organomagnesium or organozinc complexes with (B) at least one coordination compound comprising one or more carboxylate groups and/or alcoholate groups and/or tertiary amine groups, optionally in combination with zinc ions and/or lithium ions and/or halide ions, wherein the halide ions are selected from chloride, bromide and iodide, the organozinc complex comprises an aryl group, a heteroaryl group or a benzyl group when the coordinating compound is a chelating polyamine, and the reaction is conducted in the presence of zinc complexed with at least one coordinating compound when reactant (A) comprises at least one organomagnesium complex. The resulting organozinc reagents may optionally be isolated from solvents to obtain a solid reagent. The reagents may be used for making organic compounds via Negishi cross-coupling reactions or via aldehyde and/or ketone oxidative addition reactions. The organozinc reagents are stable and, due to their high selectivity, permit maintenance of sensitive functional groups such as aldehydes during cross-coupling. | 01-30-2014 |
