trans-Chlorido(phenanthren-9-yl)bis(triphenylphosphane)nickel(II)

Abstract

The title compound, [Ni(C14H9)Cl(C18H15P)2], was synthesized from the reaction between 9-chloro­phenanthrene, NiCl2·6H2O and triphenyl­phosphane in ethanol. The bond angles around the NiII atom indicate that it exists in a slightly distorted square-planar geometry.

Suzuki–Miyaura coupling reactions of aryl chlorides catalyzed by a new nickel(II) σ‐aryl complex

“…[29] Bases (Na 2 CO 3 , K 2 CO 3 , Cs 2 CO 3 and K 3 PO 4 ) were ground into powder and dried under vacuum at 125 C for 4 h prior to use. [29] Bases (Na 2 CO 3 , K 2 CO 3 , Cs 2 CO 3 and K 3 PO 4 ) were ground into powder and dried under vacuum at 125 C for 4 h prior to use.…”

“…Precatalyst 1 was prepared according to a literature method. [29] Bases (Na 2 CO 3 , K 2 CO 3 , Cs 2 CO 3 and K 3 PO 4 ) were ground into powder and dried under vacuum at 125 C for 4 h prior to use. THF was distilled over Na-benzophenone.…”

“…[26] Meanwhile, Yang reported a readily available and air-stable Ni(II) s-aryl complex as an efficient precatalyst for the Suzuki-Miyaura reactions of aryl halides and sulfonates. [29] In comparison with its known analogs with naphtharene and benzene rings, the phenanthrene ring of this complex is more highly conjugated and more electron-rich. [28] As part of our research interest in the catalytic activities of transition metal complexes, we prepared a new Ni(II) s-aryl complex, trans-chloro (9-phenanthrenyl)bis(triphenylphosphine)nickel(II) (1) (Fig.…”

“…1). [29] In comparison with its known analogs with naphtharene and benzene rings, the phenanthrene ring of this complex is more highly conjugated and more electron-rich. Herein we report the catalytic activities of this Ni(II) s-aryl complex in the Suzuki-Miyaura coupling reactions of aryl chlorides with arylboronic acids.…”
