Norbornene hydroarylation catalyzed by ferrocene palladacycle complexes

Two ferrocene derivatives containing palladacycles with bidentate (C,N) and tridentate (C,N,N) ligands were successfully used as catalysts for the hydroarylation of norbornene.

Synthesis, structure, and catalytic activity of complexes of 1,1′-bisisoquinoline with PdCl2 and NiCl2

New complexes of 1,1′-bisisoquinoline with PdCl2 and NiCl2 were synthesized. The structures of the complexes were established by X-ray diffraction. The Pdii complex acts as a catalyst for the Suzuki and Heck reactions and the hydroarylation of norbornene. As exemplified by the Suzuki reaction, the Niii complex can also be used as a catalyst.

A palladacyclic azobenzene derivative as a catalyst for carbon-carbon bond formation reactions

A bis-chelated palladacycle in which the Pd atom is [(C, N)(C, N)]-tetracoordinated to two azobenzene ligands proved to be a moderately active catalyst for the Suzuki and Heck reactions. A voltammetric study revealed that the two-electron oxidation of this complex is accounted for by the irreversible PdII/PdIV transition.

Cyclopalladated complex of 1-ferrocenylisoquinoline

A new dimeric cyclopalladated ferrocenyl complex di-µ -chloro-bis[2-(1-isoquinolinyl)ferrocenyl](C,N)dipalladium was obtained and characterized. Its catalytic properties in the Heck and Suzuki reactions (including a solid-phase version), as well as in hydroarylation of norbornene, were studied.

Palladium complexes with 1-methyl-3-phenylindazole ligands

Abstract1-Methyl-3-phenylindazole reacts with lithium tetrachloropalladate and palladium acetate to give new coordination and (C,N)-cyclometallated dimeric and monomeric palladium complexes.

Cyclopalladate complex of 3-benzyl-7-methyl-3,7-diazabicyclo[3.3.1]nonane

A new (C,N,N)-pincer cyclopalladate unsymmetrical complex of 3-benzyl-7-methyl-3,7-diazabicyclo[3.3.1]nonane (3-benzyl-7-methylbispidine) was synthesized and characterized. Catalytic performance of this complex was examined in the Heck and Suzuki reactions and in the norbornene hydroarylation.

Catalytic properties of chiral terpenoid CN-palladacycle in the C—C bond forming reactions

Chiral camphor-derived CN-palladacycle exhibits high catalytic activity in the Suzuki crosscouplings and hydroarylation of norbornene under mild conditions.

Synthesis and catalytic activity of a complex of 1,1´-bis-isoquinoline N,N´-dioxide with PdCl2

A novel complex of 1,1´-bis-isoquinoline N,N´-dioxide with PdCl2 was synthesized. This complex efficiently catalyzes the Suzuki cross-couplings and hydroarylation of norbornene.
