Subject of the invention is a process for producing a biofuel from fatty acid methyl esters (FAMEs) obtained by transesterification of vegetable oils, comprising the steps of The invention also relates to biofuels obtainable by the inventive process and to uses of ethylene for adjusting and optimizing biofuels.

Biofuel and method for preparation by isomerizing metathesis

The present invention relates to a selective method for carrying out the Buchwald-Hartwig coupling of biphenyl derivatives.

Arylation method

Subject of the invention is a process for producing a biofuel from fatty acid methyl esters (FAMEs) obtained by transesterification of vegetable oils, comprising the steps of: (a) ethenolysis of the fatty acid methyl esters in the presence of ethylene and an ethenolysis catalyst, and (b) isomerizing metathesis in the presence of an isomerization catalyst and a metathesis catalyst. The invention also relates to biofuels obtainable by the inventive process and to uses of ethylene for adjusting and optimizing biofuels.

The invention relates to a process for preparing aryl- and heteroarylacetic acids and derivatives thereof by reaction of aryl or heteroaryl halides with malonic diesters in the presence of a palladium catalyst, of one or more bases and optionally of a phase transfer catalyst. This process enables the preparation of a multitude of functionalized aryl- and heteroarylacetic acids and derivatives thereof, especially also the preparation of arylacetic acids with sterically demanding substituents.

Process for preparing aryl- and heteroarylacetic acid derivatives

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(&#x3bc;-Br)(PBu)]. The method is based on a comproportionation reaction in which a Pd(ll) compound (&#x2550;PdBr) is reacted with a Pd(0) compound (&#x2550;Pd(PBu)) in organic solvents to yield the [Pd(&#x3bc;-Br)(PBu)]compound having the Pd atoms in the formal oxidation state +1. Unreacted PdBrmay 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 R&#x2014;C(O)&#x2014;O&#x2014;CH(R)&#x2014;C(R)&#x2550;CHemploying the compound Pd&#x3bc;-Br)(PBu)]as a catalyst is disclosed.

Method for the preparation of palladium(I) tri-tert-butylphosphine bromide dimer and process for its use in isomerization reactions

The invention relates to a method for decarboxylating C&#x2014;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&#x2014;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&#x2014;C bond formation reaction.

Method for decarboxylating C&#x2014;C cross-linking of carboxylic acids with carbon electrophiles

The invention relates to a process for preparing a propiolic acid or a derivative thereof by reacting a terminal alkyne with carbon dioxide, which comprises performing the reaction in the presence of a base and a copper complex, especially a copper (I) complex having at least one ligand, at least one of the ligands of the copper complex being selected from monodentate ligands which have an aminic or iminic nitrogen atom capable of coordination with copper, and polydentate ligands having at least two atoms or atom groups which are capable of simultaneous coordination with copper and are selected from nitrogen, oxygen, sulfur, phosphorus and carbene carbon.

Process for preparing a propiolic acid or a derivative thereof

A process for preparing ketones of the general formula (III) where whereinn and m is a number in the range from 1 to 6,Mis a cation, andR has the meaning indicated for formula (III),with aryl bromides of the general formula (II)R&#x2014;Br&#x2003;&#x2003;(II)whereRhas the meaning indicated for formula (III),in the presence of two transition metals or compounds thereof as catalyst, is described.

Process for preparing ketones from alpha-oxo carboxylates and aryl bromides

The invention relates to a method for producing ketones by reacting boric acid derivates with carbocylic acid anhydrides in the presence of a transition metal catalyst. The carboxylic acid anhydrides can either be used in isolated form or produced from carboxylic acids in a reaction mixture. This method enables the simple embodiment of a multitude of functionalized ketones in a single reaction step.
