“…In particular, the (533−534), [163] (535), [164] (536), [165] (543−544), [166] (545−546), [167] (548 [168]−557), [169] (558), [51] (559), [71] (560), [161] (561), [170] (562−563), [141] (565), [171] (566−567), [172] (568), [173] (569), [126d] (570−573), [174] (574), [175] (575−576), [176] (577), [177] (578), [178] (579), [106] (580−581), [179] (582−583), [151] (584−585), [180] (586−588), [181] (595−596), [182] (597−599), [183] (600−603), [184] (604), [185] (605−608), [186] (609), [185] (610−613), [187] (614−618), [188] (619−621), [189] (622−623), [185] (624−630), [190] (631), [191] (633−635), [192] (636), [193] (637), [194] (647) [195] and (648) [196] complexes were obtained by this pathway from the treatment of the free or the in situ generated NHC The third route is the oxidation method (Scheme 15) using which the (589−590), [197] (638) …”

Synthesis, Structure, and Polymerization Activity of Cyclopentadienylnickel(II) N‐Heterocyclic Carbene Complexes: Selective Cross‐Metathesis in Metal Coordination Spheres

“…Complexes of this type display catalytic activity in aryl dehalogenation and aryl amination, [3a] styrene polymerization in the presence of MAO, [2] and hydrothiolation of alkynes. [4] The related indenyl complexes [(η 3 -C 9 H 7 )-Ni(X)(NHC)] are moderately active in the oligomerization of ethylene [5] and styrene polymerization [6] in the presence of MAO or NaBPh 4 , respectively. Other NHC-supported Ni II complexes have also been tested for olefin polymerization [7] and carbon-carbon coupling reactions.…”

Donor‐Functionalised N‐Heterocyclic Carbene Complexes of Group 9 and 10 Metals in Catalysis: Trends and Directions

“…The same group also studied the polymerisation of styrene using a Ni II complex containing an NHC functionalised with a C3-bridged indenyl group, 74. [117] The indenyl group also appeared to improve the stability of the catalyst. …”
