Syntheses, Structures, and Catalytic Ethylene Oligomerization Behaviors of Bis(phosphanyl)aminenickel(II) Complexes Containing N‐Functionalized Pendant Groups

“…Compounds 1a-e could be crystallized from ethanol in air and were stable in the solid state, but they underwent slow decomposition and oxidation in solution. [17] Scheme 1. Preparation of ligands 1a-e and 1g.…”

Synthesis and characterization of new (N‐diphenylphosphino)‐isopropylanilines and their complexes: crystal structure of (Ph2P S)NHC6H44CH(CH3)2 and catalytic activity of palladium(II) complexes in the Heck and Suzuki cross‐coupling reactions

“…Infrared spectra were recorded as KBr disks in the range 4000-400 cm −1 on a Mattson 1000 ATI Unicam FT-IR spectrometer. 1 H (400.1 MHz), 13 C NMR (100.6 MHz) and 31 P-{ 1 H} NMR (162.0 MHz) spectra were recorded on a Bruker Avance 400 spectrometer, with δ referenced to external TMS and 85% H 3 PO 4 , respectively. GC analyses were performed on an HP 6890N gas chromatograph equipped with capillary column (5% biphenyl, 95% dimethylsiloxane, 30 m × 0.32 mm × 0.25 µm).…”

“…[9] In particular, palladium catalyzes most of the carbon-carbon bond formation reactions such as Heck and Suzuki reactions, [10] which are powerful tools for the preparation of unsymmetrical biaryl [11,12] and stilbene compounds. [13] Recently, various bulky and electron-rich phosphanes have been developed as ligands to promote the cross-coupling reactions. [14] We have shown that aminophosphine and bis(aminophosphine) palladium(II) complexes offer distinct advantages over the Pd-phosphine system in the Suzuki and Heck cross-coupling reactions.…”

Synthesis and characterization of transition metal complexes of thiophene‐2‐methylamine: X‐ray crystal structure of palladium (II) and platinum (II) complexes and use of palladium(II) complexes as pre‐catalyst in Heck and Suzuki cross‐coupling reactions

“…The occupations are refined and describe the ratio of the disorder. Minor components of the DMSO molecules with occupation factors are 0.178 (11) and 0.197 (5); furthermore, the second part www.interscience.wiley.com/journal/aoc occupation factors are 0.822 (11) and 0.803(5) for Pd and Pt compounds, respectively. The positive and negative residual electron density of 1.463 and −0.806 e/Å 3 are observed at a distances of 0.70 Å from Cl1 and 0.94 Å from Pd, respectively.…”

“…[8] As well as creating highly active catalysts for these reactions, selectivity, particularly chemo-, regio-, stereo-and enantio-selectivity, is of the utmost importance. [9] The palladium-catalyzed Suzuki and Heck cross-coupling reactions are powerful tools for the preparation, respectively, of unsymmetrical biaryl [10] and stilbene compounds [11] which have been applied to many areas, including herbicides [12] and natural product synthesis. [13] Recently, various bulky and electron-rich phosphanes have been developed as ligands to promote the cross-coupling reactions.…”
