Abstract
Official abstract text for this publication.
The present invention provides a palladium(II) complex of formula (1). R 12 , m, and X are described in the specification. The invention also provides a process for the preparation of the complex, and its use in carbon-carbon and carbon-heteroatom coupling reactions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A palladium(II) complex of formula (1): wherein: Cy is cyclohexyl; R 12 is an organic group having 1-20 carbon atoms; m is 0, 1, 2, 3, 4 or 5; and X is a coordinating anionic ligand. 2. A palladium(II) complex according to claim 1 , wherein R 12 is selected from the group consisting of substituted and unsubstituted straight-chain alkyl, substituted and unsubstituted branched-chain alkyl, substituted and unsubstituted cycloalkyl, substituted and unsubstituted aryl, and substituted and unsubstituted heteroaryl wherein the heteroatoms are independently selected from sulfur, nitrogen and oxygen. 3. A palladium(II) complex according to claim 1 , wherein X is a halo group or a trifluoroacetate group. 4. A palladium(II) complex according to claim 1 , wherein the complex of formula (1) is selected from the group consisting of: 5. A process for the preparation of a complex of formula (1), the process comprising the step of reacting a complex of formula (3) with a monodenatate biaryl ligand of formula (4) to form the complex of formula (1), wherein, Cy is cyclohexyl; R 12 is an organic group having 1-20 carbon atoms; m is 0, 1, 2, 3, 4 or 5; and X is a coordinating anionic ligand. 6. A process for carrying out a carbon-carbon coupling reaction or a carbon-heteroatom coupling reaction in the presence of a catalyst, the process comprising the use of a complex of formula (1) as defined in claim 1 . 7. The process of claim 6 , wherein the carbon-carbon coupling reaction is (a) a Heck reaction; (b) a Suzuki reaction; (c) a Sonogashira reaction; or (d) a Negishi reaction and the carbon-heteroatom coupling reaction is a Buchwald-Hartwig amination reaction.
