Contributions to Organo‐Nickel Chemistry

Abstract

One hundred years of organonickel chemistry have generated a wealth of new knowledge and a history of examples of accidental discoveries which have finally led to industrial applications. The historical development is associated with the names of Mond, Sabatier, Reppe and Ziegler and, with the methods and techniques available today, many of the original discoveries and unsolved problems are attracting renewed attention. For example, 70 years were to go by before a synthesis first conceived by Sabatier could finally be realized. The path leading from nickel-catalyzed hydrogenation to highly enantioselective homogeneous catalysts is one of the contributions to organonickel chemistry which is described here.

15-Membered triolefinic macrocycles, their coordination chemistry with transition metals, and the catalytic properties of their palladium metal complexes. A review.

“…Each of them showed two strong infrared peaks in the 1898±6 and 1972±4 cm -1 regions, as required for trigonal-pyramidal complexes of the L 3 Cr(CO) 3 type. Evidence for structures 37ggg-Cr(CO) 3 and 38aag-Cr(CO) 3 was obtained by HRMS.…”

“…The nickel complexes of 2 have played a fundamental role in catalysis and in organonickel chemistry. 3 We discovered macrocycles 1 in a serendipitous manner when exploring the palladiumcatalyzed reaction of arenesulfonamides with 2-butene-1,4-diol biscarbonate (Scheme 1). 4 10-,…”

Dimerization of ethene in a fluidized bed reactor using Ni-based Supported Ionic Liquid Phase (SILP) catalysts

“…13 Homogeneous nickel complexes are well known oligomerization catalysts following a nickel hydride chain growth mechanism in which the competition between chain growth and termination via β-hydride elimination is governing the product distribution. [14][15][16] While neutral nickel complexes usually produce higher alkenes in a relative wide Schulz-Flory distribution, short alkenes are mainly obtained with cationic catalysts. 17,18 Amongst those, methallyl nickel complexes, predominantly with phosphinocarboxylates as ligands, display high oligomerzation and isomerization activities already at mild temperatures and at low ethylene pressures (see applied in a variety of reactions, both in liquid and gas phase contact.…”

Controlling nickel nanoparticle size in an organic/metal–organic matrix through the use of different solvents

“…The precursor used by Jain et al [5] and Miller et al [6] in their metal-organic redox reactions was Ni(COD) 2 , which is a widely used material with many applications [7] such as in the creation of Ni nanoparticles. Such a process is effective due to the material's labile nature and its autocatalytic decomposition from Ni(0) to bulk Ni.…”
