-
Paragraph 00187-00191, (2013/04/25)
The present application, relates to iron bisphenolate complexes and methods of use and synthesis thereof. The iron complexes are prepared from tridentate or tetradentate ligands of Formula I: wherein R1 and R2 are as defined herein. Also provided are methods and processes of using the iron bisphenolate complexes as catalysts in cross-coupling reactions and in controlled radical polymerizations.

A new phosphine-free palladacycle catalyst 4 was prepared from benzyl oxazoline in high yield and fully characterized. With it as catalyst, hydrophenylation reactions of a wide range of bicyclic alkenes, not only norbomene and norborriadiene but also oxa-
Asymmetric hydroarylation of norbornene derivatives catalyzed by palladium complexes of chiral quinolinyl-oxazolines

Chiral quinolinyl-oxazolines were found to be efficient ligands in the enantioselective palladium-catalyzed Heck-type hydroarylation of norbornene and its derivatives. The ligands with a medium sized alkyl group on the oxazoline ring provided higher enant
Palladium-catalyzed enantioselective hydrophenylation and hydrohetarylation of bicyclo[2.2.1]hept-2-ene: Influence of the chiral ligand, the leaving group, and the solvent

The use of optically active biaryl bisphosphanes 10-12, a diphenylphosphanylphenyloxazoline 8, and a (-N-sulfonylarninomethyl)bisdiphenylphosphane 7 as ligands in the Pdcatalyzed Heck-type hydroarylation of norbornene (1) with phenyl 2 and various hetaryl derivatives 3-5 leads exclusively to the formation of exo-2-(het)arylnorbornanes 6 with asymmetric inductions of up to 86.4% ee. In addition to an investigation into the effects of different chiral ligands, a systematic study has been made of the influence of various (het)aryl compounds, leaving groups, and solvents on the chemical and optical yields of this reductive arylation.
