The identity of L1 was unambiguously ascertained using spectroscopic and analytical methods. The scope of this methodology was widened and various electron-donating amines were treated with sodium 2-formylbenzenesulfonate, and a small library of 6 imine ligands L2-L6 was generated. When L2 was treated with [(COD)PdMeCI], instead of the anticipated [L2PdMe(DMSO)] complex, the formation of [(DMSO)(2)Pd2Cl2Me2] Pd Dim was observed. Nevertheless, the desired imino-methyl benzenesulfonate-ligated palladium complex [L2PdMe(Lu)] C1 was obtained by in situ abstraction of chloride and addition of bulky 2,6-lutidine as the donor group. The observation of characteristic Pd-Me protons at 0.06 ppm and the corresponding carbon at -8.1 ppm indicated the formation of C1. These 1D NMR observations were corroborated by 2D C-H correlation spectra and mass analysis, and the existence of C1 was unambiguously ascertained. Along the same lines, L4 and L5 were treated with a palladium precursor to produce [L4/SPdMe(Lu)]-type complexes C2-C3 in 55-84% yield, and their identity was established by using a combination of spectroscopic tools, analytical methods, and single-crystal X-ray diffraction. The synthetic utility of C1-C3 has been demonstrated by utilizing these complexes in the insertion polymerization of ethylene to polyethylene.</p>

An overview of state-of-the-art developments is presented to set the context. Subsequently, the significance of noncovalent interactions in these reactions is discussed in detail. Hydrogen bonding has been one of the leading noncovalent interactions that has been very frequently used in catalysis, including hydrogenation and hydroformylation reactions. Recent examples from the literature are presented to illustrate the role of hydrogen bonding in hydrogenation and hydroformylation. The impact of hydrogen bonding on catalyst development through self-assembly and the role of hydrogen bonding in directing a substrate to achieve high enantiomeric excess are discussed.1 aKoshti, Vijay, S.1 aChikkali, Samir, H.  uhttps://library.ncl.res.in/content/noncovalent-interactions-hydrogenation-and-hydroformylation01722nas a2200241   4500008004100000022001400041245011000055210006900165260000800234300000800242490000800250520087600258653002501134653002001159653001701179653002801196653002701224100002501251700002701276700002101303700002401324856013201348       2021                        eng d  a0974-362600aNi-catalyzed highly enantioselective synthesis of sulfur protected P-stereogenic supramolecular phosphine0 aNicatalyzed highly enantioselective synthesis of sulfur protecte  cDEC  a1190 v1333 aAs phosphines readily invert, the synthesis of P-chiral phosphines is a challenging task and has been rarely investigated. We report the synthesis of a nickel complex [Ni-((S,S)Me-FerroLANE)(phenyl)(I)] (Ni-Cat.1) and its performance in a P-C coupling reaction to generate P-chiral phosphine. The Ni-Cat.1 was synthesized by mixing ligand (S,S) Me-FerroLANE with the metal precursor [(diphenylphosphanyl)nickel(phenyl)(I)] in good yield. Ni-Cat.1 was characterized using different spectroscopic and analytical techniques. Treatment of racemic methyl(phenyl)phosphine (1) with 1-(3-iodophenyl)urea (2) produced the corresponding P-chiral supramolecular phosphine (3). Optimization of reaction parameters produced sulfur protected phosphine N-(3-(methyl(phenyl)phosphorothioyl)phenyl)formamide (3') with excellent enantiomeric excess (99% ee) and moderate conversion (51%).10aAsymmetric synthesis10aNickel catalyst10aP-C coupling10aP-Stereogenic phosphine10asupramolecular ligands1 aKoshti(S), Vijay, S.1 aChandanshive, Amol, C.1 aMote, Nilesh, R.1 aChikkali, Samir, H.  uhttps://library.ncl.res.in/content/ni-catalyzed-highly-enantioselective-synthesis-sulfur-protected-p-stereogenic-supramolecular
