The formation of secondary arylphosphines in the reaction of organonickel sigma-complex [NiBr(Mes)(bpy)], where Mes = 2,4,6-trimethylphenyl, bpy = 2,2′-bipyridine, with phenylphosphine

Aryl group transfer and C–P bond formation in the reaction of organonickel complexes with sodium 3,4,5-triphenyl-1,2-diphospholide

“…At low temperatures, an intense line is observed in the region of g B2. 27 with the peak-to-peak width of about 23.6 mT (this line shows splitting at g B g e ) as well as a broad line at zero fields. As the temperature increases, the broad line shifts towards higher fields (see the inset in Fig.…”

Sustainable Synthesis, NMR and Computational Study of Isobutylmesitylphosphine

“…In these reaction, however, the nickel complexes often requires certain imine ligands to be active enough [12a,b] . We previously reported on the isolation of the organonickel complex [NiBr(Mes)(bpy)] ( 1 ; Mes=2,4,6‐trimethylphenyl; bpy=2,2′‐bipyridine) which we could also characterized by X‐ray diffraction [12c] and could show that formation of secondary (mixed) aryl,aryl phosphines such as MesPhPH and Mes 2 PH proceeds in the reaction with primary phosphines RPH 2 (R=Ph, Mes) [12g,h] . This reaction results in the formation of a new carbon‐phosphorus bond involving the mesityl fragment of the organonickel complex which acts as a transmetalating agent [12]…”

Influence of N- and P-substituents in N-aryl-phosphinoglycine ligands on the selectivity of Ni-catalysed ethylene oligomerization

“…Glyoxylic acid monohydrate, aniline, diphenylphosphine, 2-anthranilic acid, methyl-2-aminobenzoate, dimethyl-2-aminoterephthalate, 3-aminopyridine, 4-aminopyridine, and 2-aminopyrazine were purchased from Sigma-Aldrich and used as received without further purification. Mesityl(phenyl)phosphine, 41 N -(phenyl) ( 1a ), 30 N -(pyrazin-2-yl) ( 1b ), 31 N -(pyridin-3-yl) ( 1c ), 32 N -(2,5-dimethoxycarbonylphenyl) ( 1d ), 33 and N -(2-methoxycarbonyl-phenyl) ( 1e ) 34 α-diphenylphosphinoglycines were prepared according to the published procedures. NMR spectra were recorded using a Bruker MSL-400 spectrometer.…”
