Patent number: 9192927Abstract: The invention provides a new method for the preparation of the dimeric Pd(l) tri-tert.-butylphosphine bromide complex, characterized by the chemical formula [Pd(?-Br)(PtBu3)]2. The method is based on a comproportionation reaction in which a Pd(ll) compound (?PdBr2) is reacted with a Pd(0) compound (?Pd(PtBu3)2) in organic solvents to yield the [Pd(?-Br)(PtBu3)]2 compound having the Pd atoms in the formal oxidation state +1. Unreacted PdBr2 may be reused in the process. The method is straightforward and applicable for industrial scale production and provides high product yields. Further, a new process for the isomerization of allyl ethers of the general type R1—C(O)—O—CH(R2)—C(R3)?CH2 employing the compound Pd?-Br)(PtBu3)]2 as a catalyst is disclosed.Type: GrantFiled: June 25, 2012Date of Patent: November 24, 2015Assignee: UMICORE AG & CO.

Patent number: 9079875Abstract: The invention relates to a method for decarboxylating C—C bond formation by reacting carboxylic salts with carbon electrophiles in the presence of transition metal compounds as catalysts. The method represents a decarboxylating C—C bond formation of carboxylic acid salts with carbon electrophiles, wherein the catalyst contains two transition metals and/or transition metal compounds, from which one is present, preferably, in the oxidation step, which are different from each other by one unit, and catalyzes a radical decarboxylation which is absorbed during the second oxidation steps, which are different from each other by two units and catalyzes the two electron processes of a C—C bond formation reaction.Type: GrantFiled: May 10, 2006Date of Patent: July 14, 2015Assignee: STUDIENGESELLSCHAFT KOHLE MBHInventors: Lukas Goossen, Guojun Deng
