Luca, Oana R.,Thompson, Bennett A.,Takase, Michael K.,Crabtree, Robert H.
, p. 79 - 83 (2013)
A series of CpNi(NHC) halide complexes are synthesized from Cp 2Ni and the azolium halide. Their X-ray structures and electrochemistry are reported.
Microwave-assisted synthesis of (N-heterocyclic carbene)Ni(Cp)Cl complexes
Landers, Brant,Navarro, Oscar
, p. 350 - 353 (2012)
The use of microwave heating for the synthesis of a series of (N-heterocyclic carbene)Ni(Cp)Cl complexes is presented. This protocol allows for a considerable reduction of the reaction times required using conventional heating, while affording comparable
Selective P4 activation by an organometallic nickel(i) radical: Formation of a dinuclear nickel(ii) tetraphosphide and related di- and trichalcogenides

The reaction of the 17e nickel(i) radical [CpNi(IDipp)] (1, IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with P4 results in a nickel tetraphosphide [{CpNi(IDipp)}2(μ-η1: η1-P4)] with a butterfly-P42- ligand; related chalcogenides [{CpNi(IDipp)}2(μ-E2)] (E = S, Se, Te) and [{CpNi(IDipp)}2(μ-E3)] (E = S, Se) are formed with S8, Se∞ and Te∞. the Partner Organisations 2014.
Complexes LNi(Cp)X with alkylamino-substituted N-heterocyclic carbene ligands (L) and their catalytic activity in the Suzuki—Miyaura reaction
Chernyshev, V. M.,Chesnokov, V. V.,Shevchenko, M. A.,Soliev, S. B.,Tafeenko, V. A.
, p. 1281 - 1289 (2021/08/10)
New nickel(ii) complexes of the general formula LNi(Cp)X (L is an N-heterocyclic carbene (NHC) ligand of the 1,2,4-triazole or imidazole series; Cp is the cyclopentadienyl anion; X = Cl, I) are reported. In these complexes, the NHC ligands (L) contain an alkylamino group at the 3 or 4 position of the heterocycle. The synthesized complexes and structurally similar complexes without an alkylamino group were tested for catalytic activity in the Suzuki—Miyaura reaction. The introduction of an alkylamino group into the NHC ligand leads to the enhancement of the catalytic activity of complexes with N,N′-diaryl-substituted NHC ligands of the imidazole series and a decrease in the activity of the complexes with N,N′-dialkyl-substituted NHC ligands of the 1,2,4-triazole series.
Anion exchange in [Ni(η5-C5H4R)(Cl) (NHC)]. Counterion effect on the structure and catalytic activity
Buchowicz, Wlodzimierz,Banach, Lukasz,Conder, Joanna,Gunka, Piotr A.,Kubicki, Dominik,Buchalski, Piotr

A series of novel complexes [Ni(η5-C5H 4R)(L)(NHC)]+A-2a-2j and [Ni(η5- C5H5)(A)(NHC)] 3a-3c has been obtained by anion metathesis from the corresponding chlorides 1a-
Reaction of nickelocene with 1,3-dimesitylimidazolium chloride
Abernethy, Colin D.,Cowley, Alan H.,Jones, Richard A.
, p. 3 - 5 (2007/10/03)
Treatment of nickelocene with 1,3-dimesitylimidazolium chloride affords the corresponding carbene complex, (η5-C5H5)NiCl(carbene) (5). The structure of 5 was determined by X-ray crystallography. The distorted trigonal planar nickel atom is attached to an η5-Cp, a carbene, and a chloride ligand. Compound 5 reacts with MeLi to afford (η5-C5H5)Ni(Me)(carbene).
